    I was having a lot of trouble installing a drivers side CV axle. I'm just not strong enough to do…read moreit. This is a repair that I needed to get done right away. After a lot bruises, scraped knuckles, some blood, sweat and tears I gave up. I started looking for a mobile mechanic. I was worried about having to wait a week for someone to come out here. That's what happened with the last guy I called to help me in a similar situation. After not showing up, then rescheduling twice he finally got to my house. His own tools actually broke while he was using them and ended up borrowing some of mine. I wasn't looking forward to another experience like that one. And being female, I'm a little leery of letting someone else work on my vehicle. I've had some not so pleasant experiences with men who thought I was clueless. I got tired of the bs stories. I started do my own maintenance and repairs. I haven't paid anyone to do anything to any of my vehicles since 1996. I called a few mobile mechanics on the list before I got to Ryan's name. He's the only one who actually answered the phone. He told me he could be here in 40 minutes. I was ecstatic! He showed up when he said he would be here. He is very friendly, has the tools needed to do the job and gets it done right away. I'm especially happy to report that Ryan didn't try to tell me stories about problems I know I don't have! Six hours after talking to Ryan, I still hadn't heard back from anyone I reached out to before him. I was about to post this review when I got an impersonal text message from one of the other mechanics I reached out to. "I can come tomorrow if you haven't gotten it already." That's it. No name, no "Thank you for contacting me", "I'm sorry I missed your call"... I'm keeping Ryan's name and number in case I need help again. Thank you Ryan!

    Beware working with Ryan. He diagnosed a starter replacement on my minivan, and recommended an oil…read morechange. Said he could get the starter the next day. Paid my deposit and never heard from him again. After repeated messages to him, 3 days later he claims to have gotten the starter, but that it was used and he would need to reorder. Proceeds to reorder and then goes silent again. Only after I threatened legal action did I get a response, almost a week after I paid my deposit. After replacing the starter and doing the oil change the car stops working within a day. Towed it to a reputable mechanic who says that Ryan short changed the car 2 quarts of oil, causing irreparable crankshaft and cylinder misfires. Basically, the engine blew because there wasn't oil.

    I spoke with Myron and he was able to schedule an appointment for me 3 days in advance for a…read morepre-purchase inspection and compression test since I'd be driving in from Dallas. On the day of the appointment, he cancelled 20 minutes AFTER he was supposed to arrive. I attempted to call him multiple times at least 3 hours before the appointment and on the day of the appointment. I'm very disappointed in the professionalism shown. If you're no longer available, please inform me of that as soon as possible. Don't wait until after the appointment to notify me that you will no longer be coming.

    My friend and I were driving alongside the highway when our tire blew. There really aren't a lot of…read moreoptions in the Waco area, so I used Yelp to find the closest option. Regardless of how fast these people can change a tire, it'll may still take a bit for them to drive out to you. We were 20 minutes out of Waco and it took about 35-40 minutes for our person to show up. I'm not sure how many people actually work here since the person who took my call was also the person to come change our tire. I ended up having to ping him my location since I was having difficulty figuring out where exactly on the highway we were. He worked quickly, was knowledgeable about the situation, and was very friendly the entire time. When we were billed, he said he was an independent contractor so he negotiated the price with us. The total ended up being $75, which I think is pretty reasonable considering how quickly he worked and how much less expensive this was than calling a tow truck.

    Finally a auto repair shop that doesn't OVER CHARGE the customer! If you want great customer…read moreservice, a friendly atmosphere and fair pricing...this is the place to go. Past it on!

    I Live in Austin and I was visiting family in Killeen so I decided to get my car Windows…read moretinted.It's cheaper to do in Killeen Than Austin.I called a few places and Honestly decided to go with Deepstage because they were the least expensive place.I called while on my way and He said they could get me first thing in the morning and I explained that wouldn't be possible bc I was only in Town for a couple hrs.He told me to go ahead and bring my car in and that the tint guy (Kevin) could do 2 cars at once.The only bad thing I could say is I waited about 3 hrs But I was just happy they fit me in so waiting really diddnt bother me.The 2 guys at the front were super Awesome! Really good customer service! When it was done Kevin went outside with us and told us the do's and dont's for the next 3 days to not mess up the tint.Which I also thought was Awesome! To top it all off when I paid he had explained to me since we looked them up on the web they gave us $20 bucks off an already great price for a promotional special!!! We tipped Kevin left and the car looks great! If we have any other cars that we need tinted Im not going to think Twice about Driving to Killeen and having Deepstage do my tint! They do other cosmetic stuff to cars alo but diddnt really ask what.Great experience!! Thanks Deepstage motorsports!!
