- No tow truck needed. Most "won't start" jobs get fixed in the driveway.
- Diagnosed on-site. Real codes, real test results — not a guess.
- Saves you a day. No rideshare home, no shop wait, no shuttle.
- Mobile for safe jobs, shop for major repairs. Right tool for the job.

Diagnose Before We Fix
We Don't Guess. We Diagnose.
Half the shops out there throw parts at it until something works. That's how a $90 fix turns into $900. Here's how we run it instead.
- 01
Listen
What happened, when, what changed. The story matters as much as the codes.
- 02
Scan
Pull every code on the bus — engine, trans, ABS, body. Not just the dashboard light.
- 03
Test
Multimeter, scope, pressure gauges. Confirm the code matches reality.
- 04
Quote
Parts, labor, total. Up front. You decide before a wrench turns.
- 05
Fix
Right the first time. Verified after with the same tools we diagnosed with.
Every Vehicle Class
Built for the Job, Whatever It Is
Most mobile mechanics max out at passenger cars. Big Tee runs full capability across three tracks.

Real Calls, Real Fixes
From a Parking Lot. From a Driveway. From Monday Morning.
My car died in a Kroger parking lot at 9pm. Big Tee rolled up in 40 minutes, found a bad starter relay, and had me driving home by 10:15. Saved me a tow and a tow-yard nightmare.
Marcus W.
Decatur, GA
I called three shops about a 2014 box truck. They all said 'bring it in.' Big Tee said 'we will come look at it.' Diagnosed a wiring harness issue in the driveway. Real one.
Janelle T.
Stone Mountain, GA
Wife's SUV wouldn't start on a Monday morning. Big Tee was there before lunch. New battery, alternator test, done in 45 minutes. Didn't miss a meeting.

Straight Answers
Quick Questions, Straight Answers.
How fast can you get to me?
In Decatur, usually same-day. Metro Atlanta, typically next-day or sooner. Call and we will give you a real time window.
What can you fix on-site?
Most diagnostics, batteries, alternators, starters, brakes, AC recharges, sensors, belts, hoses, and most 'won't start' problems. If a job needs a lift, we pull it into the shop.
Do you work on trucks?
Yes. Pickups, box trucks, semis, and small fleets. We are one of the few mobile operations in Metro Atlanta that does heavy-duty commercial work.
What if I can't drive the car?
That is exactly what we are built for. Stuck in a parking lot, dead in a driveway — call us before you call a tow. Often we can get you moving without one.
Do you come to parking lots?
Parking lots, driveways, job sites, apartment complexes, office lots — wherever the vehicle is, as long as it is safe to work.
How do you estimate costs?
Diagnostic first, then a straight quote before any work starts. Parts cost, labor cost, total — all in writing. No surprises.
