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

Pre-Purchase Inspection
Buying a Used Car?
Don't Sign Anything First.
Dealers won't tell you what's wrong with a car. Private sellers may not know. A Big Tee pre-purchase inspection puts everything on the table before you hand over your money — or walk away from a lemon.
We'll come to the seller's location, run a full diagnostic scan, and give you a straight report on what the car actually needs. No upsells. No pressure. Just the truth.
Schedule an Inspection (770) 780-0730
We come to the seller's location — dealer lot, driveway, wherever the car is.

- Transmission & drivetrain
- Brake system & rotor wear
- Suspension & steering
- Electrical systems & battery
- AC, heat & climate control
- Full OBD diagnostic scan

06
Straight Quotes
Numbers up front. No surprise fees. If it's bad news, you hear it first.
No Surprises
Here's Exactly How Our Pricing Works
Every mechanic says they're honest. We show you how — before work begins.
Diagnostic First
We scan and inspect before touching anything. You know exactly what's wrong — and why — before we quote a price. No guesswork, no parts-swapping.
Written Quote — Before Any Work
Labor, total, and any part we source for you — all in writing, all before we turn a wrench. Most customers buy their own parts. You approve the quote or you walk, no pressure either way.
Quote Is The Price
What we quoted is what you pay. No "we found something else" add-ons. No shop fees or disposal charges. The number on the paper is the final number.
Diagnostic Fees
Diagnostics are billed by the hour. On repairs of $300 or more in labor, that time is credited toward the repair when you approve the work at that visit.
Standard Diagnostic Engine, brakes, suspension, drivetrain, OBD scan
$100/hr credited on $300+ repairs
Electrical Diagnostic Wiring, sensors, modules, charging system, no-start electrical
$150/hr credited on $300+ repairs
Electrical diagnosis takes more time and specialized test equipment — that's why it's priced separately and clearly up front.
The credit applies when you approve the repair at that visit — it can't be banked for later. If you don't go ahead, the diagnostic is due before the vehicle is released. Full diagnostic policy →
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.
★★★★★
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.
★★★★★
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, dump trucks, box trucks, semis, work vans and small fleets. We are one of the few mobile operations in Metro Atlanta that does heavy-duty commercial work, and you do not need a fleet — one truck is a real customer.
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 or text 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 — all in writing, no surprises. The diagnostic is billed by the hour and is credited toward the repair on jobs of $300 or more in labor when you approve the work at that visit. Most customers buy their own parts, so quotes are for labor unless we source a part for you.
