Awesome work and service!!! Alex is a great mechanic and was able to do my big brake kit on my Tiguan. He truly knows it all will keep going there for all my services.

Very unhappy with what I got from this guy I told him I had a thirty year old outboard that ran, but I changed a couple of the electric parts, and now I can't get it to run! He comes over, he does a compression check.It's a thirty six year old motor it's gonna have low compression, it's not a race boat! Charges me a hundred dollars and say, hey, you gotta low compression motor and then leaves! He says he would give me back my money or he'd come back and do whatever to make me happy.But now he ignores my phone calls! Then, he try to work on my hundred thousand dollar truck.But if he can't work on a fifteen hundred dollar thirty six year old motor why would I ever let him touch my hundred thousand dollar truck

I’m SO happy that I FINALLY found a KNOWLEDGEABLE mechanic who COMES TO ME! Very smart, VERY reasonable in pricing (out of ALL the multiple quotes I got he was by far the best price!), and I really felt like there wasn’t anything he couldn’t do! I hired him to replace my brakes and rotors on my 2019 Jeep, and threw a few other “wants” out there as well to see if he could do it all! To my surprise he said YES! So not only did he address my main concerns, he removed some odd aftermarket wiring the was messing things up, fixed some lose headlights, installed my CB Radio AND installed my dash cam that has been sitting in a box for years! Not only did he do all of that in LESS THAN a few hours but he also did it for less than the quotes I got JUST for my brakes and rotors from other companies! OH! And did I mention HE COMES TO YOU!! I would recommend Alex to EVERYONE! I’m looking forward to seeing him grow as an independent entrepreneur! GO ALEX, AND THANK YOU! THIS REAL ESTATE BROKER IS GRATEFUL FOR THE CONVENIENCE AND THE SAFE RIDE!

You name it & this guy can do it! Great mechanic & very professional! Highly recommend !

In a word, WOW... Showed up on time as scheduled. Quickly assessed the issue and resolved the problem efficiently. He virtually diagnosed my problem based on a conversation. He was right and had the repair done in under an hour. Then he proceeded to provide further details about things I wouldn't have thought of in the first place. He not only fixed the issue but checked other things to ensure everything would be okay for me after he left. He let me know if I had any problems just reach back out and he would help me. He wasn't just there for the money. He cared about helping me out.. Hard to find these days.

I had my cp4 fuel pump replaced with an DCR on my SuperDuty and couldn’t be happier with the service. Alex was professional, knowledgeable, and got the job done quickly. My truck runs smoother than ever, and they took the time to explain everything to me in detail. Great pricing and honest work—I highly recommend them for any diesel repairs.

Alex is the man! Extremely professional, knowledgeable and efficient. Top notch workmanship on my Silverado SS! Highly recommended!

Awesome pricing, I got a ton of work done on my f250 and he had it fix and running with in the week would definitely recommend.

Great Mechanic, Highly recommended!
