I've been going to Mark for about 12 years now. Bought a 74 Karmann Ghia from him in 2001, and have…read moreused him for parts ever since. Mark always manages to surpise me with what aircooled parts he has in stock, or can get quickly. I've bought everything from wire connectors, to floor pans from him, and everything in between. Mark has always been great to me. Even going so far as to give me parts for free as long as I take them off the car they are on myself. He has offered me repair advise, and I've refered people to him multiple times now. It's great to not only have a local guy who fixes and stocks parts for older air cooled VWs, but actually knows how to fix them the right way.

Where do I begin? My…read morerental car got hit in the rental drop off area of their parking lot. Instead of reviewing the security camera like I requested , they avoided my call. In the end I had to pay for the damages when this clearly happened after I gave them the keys, which was only five minutes to closing. Enterprise called me the very next morning because someone backed into the bumper of my rental. Royal took no accountability. Even after all of this, they did a botched job on the body of my BMW by using mostly after market parts to appease the insurance company instead of whats ascetically best . The work was so bad I had them redo my front bumper and even afterwards, I still wasn't entirely pleased with the results. After this nightmare, i still held back on writing a bad review until I recently went to bmw to get my lights replaced by. They pointed out how the headlights were not installed properly but glued on. Yes, glued on! This angers me tremendously because I pointed out how the lights looked improperly installed but they dismissed my claim. Do not come here!!

He…read morealways works closely with me to keep me informed about the progress of my car and one time even worked through the night so I could have my car back so I could get to work the following day. He is always able to explain everything (even to a novice like me) and always helps me to decide which services are absolutely necessary at that time and which could wait. I have taken my car back several times and have referred him to numerous friends. For once, I don't feel like I am being ripped off like I do at other auto shops and my 2001 car has never run better. Plus he is within walking distance to Rockille Metro.

Everyone knows that finding a good car mechanic is like finding a good plumber or electrician or…read morecarpenter - easy in theory, difficult in practice. You'll end up with a friend of a friend, or that guy your cousin used in 1991 whose rates have tripled, or the guy whose mantra is "don't worry, I got this" So it's with a lot of surprise and pleasure that I report that I finally found a good car mechanic who meets the holy grail of criteria: honest, smart, good people person, nearby, good rates, great front desk. Eric is the mechanic, and he not only knows which way is up on your car (not always a guarantee, trust me), he will explain why it is up and not down and how it might be even more up, in plain English, in a completely understandable way. Not a common skill, believe me. He clearly is all about cars, is a total car person, and I'll be having him do everything I can't do myself from now on. Kristyn is up front and took care of things lickety split. Smiles, laughter, and good vibes great you when you walk in, which also is a pretty rare thing in the scowl-heavy world of mechanics. She's a gem. One last note: the garage is incredibly clean. I have spent a lot of time about cars and mechanics generally and I have seen some stuff in my time, and Eric's garage is by far the cleanest I've ever encountered. No black smudges on the floor, all tools in their rightful place, everything seems color coded or to be in a purposeful place... I was impressed. The real deal, ladies and gentlemen - a really great car shop.

Automotive Essentials is also LED Cycles. I first met Doug Perez, the owner of LED Cycles/…read moreAutomotive Essentials at Hagerstown Bike Week several years ago. I wanted my burnt orange Harley Davidson Road King Classic to have an iridescent orange glow when I rode at night. It's safer and just awesomely cool. There were several vendors there who did this type of work. But after looking at LED Cycles' set up, and the quality work they were doing, I decided to sign up with them. I liked the way they ran their lines. I liked the way they hid what you should not see and highlighted what you should see. And I especially liked the professional on/off switch that purposely did not tie in to the bike's factory electronics. This avoids any potential issues if it should fail. They were busy, but got my bike done in reasonable time. Doug let me know he stands behind his work. And I rode off a happy customer. A couple of years later I had one strip that was starting to come off a bit. I called him up and he said he was going to be at Gettysburg Bike week. I showed up there, and even though he was swamped with business, he warmly welcomed me and replaced it promptly. Off I rode again. A happy customer. Now, one year later, it turns out my mechanic must have damaged the lights when removing my gas tank. I called Doug up and he said he has a shop set up at his house and does installs there. He asked if I could come by on Sunday at 9am and he will provide breakfast. When I showed up on Sunday, his house was easy to find. It was the one with all the impressive trailers, trucks and beautiful line up of Harleys waiting to get their lights done. His set up is quite impressive. It is a cross between man cave, Harley work shop, and thanks to his wife, bed & breakfast; or should I say, bikes & breakfast. I only wish I took some pics. As soon as my helmet came off, his wife was asking if I would like some coffee. There was a table set up with table cloth and place settings where breakfast was about to be served. It quickly became clear this was going to be more than a muffin. First came higher end pastries. Then his wife who loves to cook made delicious western style omelets for everyone, all the while making sure our coffee was topped off. And it was the good coffee too. I could not believe I was getting served a four course breakfast complete with fresh fruit cup, some kind of yummy sausage ring loaf, and a perfect omelet that was exceptional. I felt like I was at Harley Davidson, Ritz Carlton! I was so full I had to turn down the last course of her home made Orange Julius smoothie for "desert". What a perfect morning. A nice hour long, morning ride over. Good conversation with fellow bikers as we enjoyed a gourmet breakfast as our bikes were getting worked on by Doug and his associate. Doug replaced the necessary parts to get the lights working again. And I could not believe he would not charge me. Unbelievable! I felt a little guilty after enjoying such hospitality. And so once again, off I rode, a happy customer. But this time, a happy customer with a full belly and a sincere appreciation for this one in a million customer service. So, take my advice, if you want those cool night time iridescent lights or other popular biker accessories, give Doug a call. And if your smart, you'll show up at the man cave location for his wife's famous breakfast.

I got hooked up with Automotive Essentials by USAA, my car insurance company, after my first car…read morestereo had been stolen. Jason put in the new stereo and everything worked perfectly. A few months later my SiriusXM, part of the new stereo console, just up and completely stopped working. Ahh! I contacted Jason asking if he could take a look and see what the problem might be, he was the one who installed it so I trusted he would be able to find the problem. I drove it to his garage, he played around with it for awhile and the XM connection was back up again after about an hour. He graciously offered to drive me back home so I didn't need to take a taxi while he worked on it, which was very thoughtful. He charged me $30 to fix the connection which I didn't mind. But as soon as I got home, parked the car and turned it back on again the XM connection completely died again. WTF!? Very weird. So I texted him again, asking if he would take another look at it again. In addition, I called XM to make sure everything was cool with the connection on their end, which it was. XM also sent me a small car radio gratis in case the one inside my stereo stopped working again. I texted Jason saying, hey, I have this new little XM radio, would you be able to connect it for me without charge? This is not a complicated install but I didn't feel confident that I could do it myself due to having to connect the antenna piece and that's why I asked for his help. I paid him for the first time he tinkered with the faulty connection but ultimately the connection was never restored. I didn't get any response, even after texting on a few different occasions. Jason didn't seem interested in helping me anymore after I asked him if he would connect this second radio free of charge since he wasn't able to solve the problem after I paid him the first time. I feel like he dropped the ball, wasn't willing to help, and that he should have offered to fix my XM connection until he got it right. Now I have to take the car to a different place, pay again and hope that the issue gets resolved. The experience was disappointing.
