Why people drive past three other shops
Three things we do differently.
01
We publish our prices
Every common job is listed on the Pricing page at a flat rate. No estimate roulette, no “bring it in and we'll see.”
02
The right tools for the badge
ISTA, ODIS, and PIWIS — the same software the dealer runs, so we read the same fault codes instead of guessing at them.
03
You approve every line
Photos of the actual problem, sent to your phone, before any work is authorized. Nothing gets done because we assumed.
What we do
Six things that cover most of what comes in.
MNT
Scheduled Maintenance
Oil, filters, fluids, and plugs on the interval your engine actually needs — not the one that sells the most services.
From $189
Learn more → BRK
Brakes & Suspension
Pads, rotors, control arms, and air suspension. We quote OEM and quality aftermarket side by side and tell you which matters.
From $420
Learn more → ENG
Engine & Drivetrain
Timing chains, VANOS solenoids, turbo and charge-pipe work, clutch and DSG service — the jobs most independents send away.
Price Quoted per car
Learn more → ELE
Cooling & Electrical
Water pumps, thermostat housings, and the intermittent electrical faults that three other shops have already given up on.
Labor $165/hr
Learn more → PPI
Pre-Purchase Inspection
Two hours, a lift, and a written report with photos before you hand anyone a cashier's check.
Flat $225

How it works
Four steps, and you approve the one that costs money.
1
Drop off or book a loaner
Tell us the symptom in plain words. You don't have to know what's wrong — that's the part we're for.
2
Diagnose on factory software
$145, and it comes off the bill if you have us do the work.
3
Approve the estimate
Photos of the actual part, a flat-rate price, and a completion date. Text back yes or no.
4
Pick it up
Every line explained. Old parts in a box if you want them.
