They put a performance downpipe and intake on my Subaru WRX. The work was very professional. Price was a little steep though for 3 hours labor ($417). They did a great job though. I would definitely use their services again.

Great place! Very reasonable and honest! Great communication about the vehicles and options and prices before just fixing it and slamming you with a bill out of nowhere! Would definitely recommend and stay supporting our local small businesses! Great job Steve! Keep up the great service!

Professional staff, great atmosphere, and affordable prices.

I recently moved to Maryland and needed a MD inspection completed on my vehicle. I was told my tint was too dark and needed to be removed to pass. I MADE the decision to have the tint and it was my responsibility to have it removed, the guys did it for me. Great business and great people. Highly recommend.

Steve is the best! Ive had a few jobs done here, and every time, his estimate was higher than what I paid. Always a nice surprise! Good warranty. Friendly folks. Highly recommend.

Was able to fit me in and repaired on short notice. Greatly appreciated it!!

Cant say enough good things. Have been a loyal customer since the beginning. Steve and sandy treat me like family. I value them greatly. Easy to get appointments. Super quick service without jeopardizing quality and expertise. Super affordable.

This repair shop was recommended to me, and must say that I am impressed with the results and workmanship. The professionalism they displayed was outstanding. The prices are not as competitive as you might think. Actually, they are cheaper than most repair facilities. And, I got three ( 3 ) estimates for the same repair. Guaranteed Truck & Auto Repair has a customer for life.

Steve and his men are the best the state of Maryland has great service and fair prices.

I want to take a minute to give steve and his crew a review. I found his auto shop in October when my 05 pathfinder was making a noise steve went out of his way to take a ride with me right away and tell me what the problem was which was a universal joint within 3 hours I was there and gone with my truck fixed at a affordable price. 3 months later my family member had a motor go out of a 2012 honda odyssey, steven then gave us his honest opinion of what to do with the vehicle, we took his advice and where to get the motor and of course he had it up and running smoothly within no time at all,sad to say that 2 weeks ago my motor went in my pathfinder once again steve was amazing with the advice he gave me and had me up and running with a new motor with 100k mile warrenty. I refer all my friends and family to his shop he is a go getter and will help you with all ur needs. Not that I want to ever have to but the next time I have a issue he will be the one I call. Thank you steve and your crew for the job you do

CANNOT say enough good things about this place !! HONEST, KNOWLEDGEABLE and good prices........Steve and his staff know wth they are talking about....i trust them 100%.....and give them the highest of praise.....if you need a repair from a whole engine (which i did) on up....they know what they are doing !!!

The took great care of the timing chain in my little Honda. Very pleased!

Great service went in for a tire repair first time I have seen tech confirm and the use a torque wrench to apply the correct specifications.

Awesome place! I recommend this place to anyone with a vehicle. not only can they diagnose your vehicles problem they are reasonably priced.

Good Honest Repair shop Give em a try !!!

I have had my car repaired there a few times, hoping the experience would improve but it didnt. Their customer service & integrity sucks from the front of the office to the back of the shop. I often hear about businesses struggling and going out of business if this happens to Guaranteed Truck & Auto I would not be surprised or shocked. In short they will never receive another dime from me.

These guy are great honest small town machanics that know what they are doing. Reasonable prices too

Very hardworking and honest garage. Went above and beyond to help me get a used tire on my VW Passat. Highly recommended!!!
