What We Fix
Expert service on Japanese and domestic vehicles. We do not service newer European models (BMW, Mercedes, Jaguar).
AC Repair & Recharge
This shop has been Mableton's AC specialist for 35+ years across two owners. We diagnose and repair everything from refrigerant leaks and compressor failures to evaporator core replacements. If your AC isn't blowing cold, we know exactly why — and we fix it right. No guessing, no parts-cannon approach.
Electrical Diagnostics
Mysterious warning lights, intermittent faults, no-start conditions. Electrical problems are where most shops give up — and where we specialize. We use professional-grade scan tools and real component testing to find the actual fault, not just clear the code.
Preventive Maintenance
Oil changes, fluid flushes, belts, hoses, filters — done right with OEM-grade parts. We won't upsell you. If it doesn't need it, we'll tell you. If it does, we'll show you.
General Repair
Brakes, suspension, cooling systems, exhaust, and more. We service Japanese and domestic vehicles only. If another shop told you they can't figure it out — bring it to us.
We Charge $150 to Diagnose Your Vehicle.
Here's Why That's Good For You.
A lot of shops pretend to diagnose for free — then charge you for the wrong fix. We do it right the first time, and we charge for the expertise that makes that possible.
The $150 fee is non-negotiable and required at booking. It applies toward your repair if you proceed with us.

This location has been Mableton's AC specialist for over 35 years across two owners. John Wanarski took over in 2008 and built the shop's reputation on one thing: solving problems other shops can't.
Other mechanics send John their hardest diagnostic cases. No upsells. No shortcuts. OEM-grade parts only. When you bring your vehicle here, it gets John's full attention — not a rushed assembly line.

“John figured out an electrical gremlin that two other shops couldn't identify in three weeks. Had it diagnosed in a day, fixed by the next morning. The $150 diagnostic fee is worth every penny.”
“My AC stopped working in July — worst timing. JW Auto had it diagnosed and recharged same week. Been blowing ice cold ever since. This is my shop now.”
“My mechanic actually referred me here when he couldn't solve a no-start issue on my Tacoma. John found the problem in two hours. Straight shooter, no nonsense.”
