I came here for a safety inspection. I could tell upon walking in that this place was well organized. My appointment details and paperwork were already organized and ready. Waiting area was well maintained and clean and prices are very fair. Would definitely recommend this place and come here for other services.

Tom McNicholas

Honest. I can't tell you how valuable it is to find honest and competent mechanics. They were pleasant to deal with, made things easy and convenient and worked thoroughly and quickly.

Moises Aguilar

This is the best place to take your car. Guaranteed work, and Roy and Dave's kindness is top-notch. God bless you, guys.

Evan Silverberg

stoked to finally find a place that can align my car properly. the owner Dave worked with me to get my alignment 100% on my evo. I was so impressed that i scheduled another appointment for my other car. If your mechanic is sub par definitely check out FAST of West Chester.

Worked with Roy, he set up my 2020 Tesla Y with Koni Active Special Red Shocks. Roy was super responsive & clear with some of my questions. He had my parts ordered & installed in a matter of days. He was the only one that disqualified a prior part that other shops quoted but wouldn’t properly fit my car. Even though I spent more than I wanted to (all the shops were right around same price) FAST WC was upfront & no surprises with cost & now enjoying the much smoother ride for sure. Nice job!

Wyatt

Very painless and fast service. Had an alignment done on my C7 and had it bad in a few hours! Appreciate the dropbox system too, I was able to drop it off safely before opening hours

Dean

Amazing work every single time. Wouldn’t trust my car with anybody else. They take pride in their work and are honest. Lowell is the man if you need anything done!

Jon Wagner

I have a 1995 Mitsubishi that has had engine problems for the last few years. I haven’t been able to find anyone that would take on the work, let alone fix it. Until I found FAST.

The team at FAST listened to me about the issues, ran diagnostic tests, did additional research, and fixed the problem. They even found and fixed a bunch of turbo issues that were sapping power from the car. The car drives like it is new again.

They are now the go-to shop for me!
