Went into Honda for my oil maintenance and afterwards the service advisor told me that my struts…read morewere blown. They typically need replacement anytime after 80k miles (we had 128k) but I was not prepared for the major expense and a reschedule. Long story short, I was in a bind and explained my situation (time, money, and my daughter needed the car) to Mike; he did a few preliminary visual checks, squeezed me into his tight schedule, quoted me significant savings and also gave me a AAA discount, finished by the end of day, and provided me a loaner. Mike got me FCS struts w/ 3 years warranty. Really good and caring folks at Phil's Pro Auto Service, in Greeley CO.

I called Collins to see what they could do for me, since I did not get what I paid for and the answer was. No, it's done and nothing I can do for you. A shop like them should at least offer partial refund or something to make a customer happy. They must not care about their customers. Would never go back or recommend anyone else to go either. That's not even to say they over price their service. Good luck everyone and stay safe! God bless you all

Come to fine that he is also proficient with Jeep and Subaru as well. I have gotten to know Jon over the past year and am more than pleased with his knowledge and abilities to evaluate my cars. The major issue we've dealt with has been what's known as a TIPM which basically is the control computer onboard to which all electrical is connected. Very technical and delicate but he's gotten me heading in the right direction. What I first learned about him is that integrity is of the greatest importance. Because of his deaership experience he is very knowledgable and efficient with his time and tools. An experienced person as myself can evaluate mechanical skill by the way a person works. I pride myself also with the ability to tell when a person is being honest. When dealing with pricing, a skilled mechanic can finish a job while others are just beginning. I highly recommend Jon and look forward to using his service again when needed.

BUT RELIABLE SERVICE LMAO I THINK NOT Asked for invoice in the 23rd said he would send it still never received it! Have no reason to lie about that! DO NOT USE THIS SHOP! Have you ever seen a shop be so condescending and rude instead of help fix the problem! Yikes! Found Mj's Auto service on Facebook. Talked to John about what was going on with my car. I told him specifically that I needed all the leaks fixed. He gave me a quote and said he needed half the money up from for parts. I (knowing women get scammed a lot) said no that's okay I'll find someone else to do it. I knew something was off. But he convinced me to go with him and on my better judgment I did. I had taken a loan out for $3,000 and told him not to go over that. Probably another big mistake! Because he took me for all my money! He had my car over 2 weeks! And still wanted to keep it for longer. He conveniently stated moving into a new shop after I gave him all of my money and that was his main priority instead of getting my car fixed. If wasn't up for the task he shouldn't have taken on this project! Didn't fix all the leaks like I asked. And still tried to say I owed him more money. On top of my temperature gauge not working anymore and my wiper fluid canister broke and this piece of hanging tube he said "just go to the junkyard and get the piece that's missing!" And my transmission fluid still leaking! Excuse me but if you are working on my car and break or misplaced something that's your job to fix it! I can't tell you how unprofessional that is and to say he is reliable and has 5 stars but treated me like I was nothing took all my money and still didn't fix my car to say I'm pissed is an understatement! I asked for an itemized receipt and still have yet to receive a receipt of any kind of proof of work that he's done on my car. I don not recommend this guy for work especially if you are a woman! He takes advantage of woman. I knew I should have gone with my gut because I knew he was going to screw me! Also I called him to express my concern and he would not let me talk made up some bull crap lie and also recorded our conversation! So yeah I was mad but he's was rude and interrupting! And now his girlfriend is attacking me personally! Never talked to her before! She knows nothing about the situation yet she's being insulting to me! Says a lot about the people they are over a bad review!
