About Roy’s Mobile Mechanic HQ
Real Experience.
Real Automotive Solutions.
Eight years of full-service automotive repair in San Antonio — from routine oil changes to complete engine and transmission rebuilds.
A Shop That Takes the Whole Job
Roy’s Mobile Mechanic HQ has spent eight years keeping San Antonio drivers on the road. In that time the shop has handled just about everything a vehicle can throw at it — oil changes and scheduled servicing at one end, complete engine and transmission rebuilds at the other.
That range is the point. Plenty of shops will take the routine work and send the hard jobs down the road. Here the diagnosis, the repair and the rebuild happen under the same roof, which means one point of contact and one shop accountable for the result.
Bring the vehicle in, describe what it is doing, and you will get a straight answer about what is wrong and what it will take to put right. Warranty options are listed on your receipt.
