Rialto's most trusted mechanic, one honest diagnosis at a time
Our story
GST Auto Service Technicians is a Rialto auto repair shop built around one idea: tell customers exactly what's wrong and exactly what it costs to fix it. Steve and the team walk every customer through the diagnosis step by step, so there are no surprises and no upsells.
We work on everything from full-size trucks to European imports. When a customer brought in a 2002 GMC Yukon with a stubborn misfire nobody else could pin down, our diagnosis identified a worn cam lobe and lifter, the answer that finally let him fix it right.
Fair pricing and straight talk have built our reputation one referral at a time, including from the tow truck drivers who see a lot of shops and choose to send their own customers to us.
What customers say
“The owner is so kind and honest. Takes the time out to explain the details of the work needed. Very reasonable prices!”
“I cannot speak high enough about Steven. Literally the best around. Cares about his people and his community. I'd refer anyone to him. I've taken my truck to him multiple times over the years and I've learned so much. It really shows how much he cares and he's honest about what's going on. Quality speaks for itself when even the tow truck drivers let you know you're going to a good place.”
“I dropped my truck off and after a couple of days Steven gave me a call to come by, and he confirmed my suspicions, he said it was the cams. I slapped it back together with all new gaskets, lifters, lifter trays, and a cam. I started her up and voila, no more misfire. Steven's diagnosis was spot on, and I'd recommend him highly if you ever need an expert with vehicles.”
