Good local store with some very nice employees. If they don't have your part in the back they can get it quick (even during this crazy time). I was happy with the prices as well.

Service and prices so much better than Napa. Sometimes half the price especially on quality brake rotors/parts. Ever since using these guys I avoid Napa at all costs.

I've been going to Mark's United Auto Parts for over 35 years and if they don't have the part you need, they'll get it for you FAST. You know what's awesome about them? THEY'RE RELIABLE and they provide EXCELLENT CUSTOMER SERVICE! Those "other guys" can't find their way down the aisle, nevermind looking up the right part to begin with, then ask you "does this look right to you?" Mark's United Auto truly deserves a 5 star rating, and is also a great place for your auto body and painting needs, too. Just an honest, unbiased, review. Thanks, guys.
