Who shows up

Two owners. No strangers.

You are handing someone your keys and your driveway. Here is exactly who is going to be standing next to your car.

Jay Metcalf, Owner & master technician at Game Changer Automotive

Owner & master technician

25 years · ASE certified · gas & diesel

Twenty-five years of it, and he still runs the calls himself. Dealer certified on Ford, GM and Chrysler diesel, and the person who diagnoses your car, turns the wrench and stands behind it.

Certified technician

Came on as a partner this year. He runs his own service calls and does the repairs, on his own line — so whoever you get, you get an owner.

Same two people, every visit. No rotating crew, no subcontractor, and nobody you have to explain your car to twice. Read Jay’s story

The Scan

Tell it what your car is doing.

This is roughly the conversation you’d have with Jay on the phone. Pick the symptom and see what it usually turns out to be — and what he does about it.

Select a symptom

Common causes, not a diagnosis. Nothing replaces putting a meter on your actual car — which is exactly what the $125 diagnostic is for.

Why mobile

The shop was never the point.

A building full of lifts exists so a shop can work on twenty cars at once. It has nothing to do with fixing yours better. Almost everything short of an engine rebuild can be done properly in your own driveway — by somebody who is only working on your car.

The usual way

  • Drop it off before work, hope for a ride home
  • Sits in a queue behind eleven other cars
  • You talk to a service advisor, not the tech
  • Diagnostic fee, whether or not they find it
  • Called at 4:45 with a number and no photos

With Jay

  • He comes to your driveway, your office, your parking lot
  • Yours is the only car being worked on that visit
  • You talk to the man holding the wrench
  • $125 diagnostic, waived when you have the repair done
  • Photos of what he found, sent to your phone

Two techs, no middlemen

You get an owner. Every time.

Twenty-five years, ASE certified master technician, and nobody in between. The person who answers the phone is the person who diagnoses your car, turns the wrench on it, and has his name on the truck.

Gas and diesel both, and dealer certified on Ford, GM and Chrysler diesel — so the work truck that pays your bills does not have to go on a rollback to get looked at.

Jason Garcia came on as a partner this year — a certified technician who answers the phone too, runs his own service calls and does the repairs. So there are two of them now, and they are both owners. You still never get handed to a stranger.

That’s the whole business model. It’s also why they can afford to tell you a repair isn’t worth doing — there’s no service advisor upstairs with a monthly number to hit.

Mr. Metcalf went out of his way to ensure I made my trip coming up safe and sound. He inspected every part of my vehicle and even taught me lessons regarding my vehicle and how to keep it running strong. I highly recommend.

Pre-trip inspection

Truck was down several months due to brake issues, had it at several shops with no luck, the brakes were locking up, changed everything. Jay got on it and busted his butt, and figured it out. I'm completely grateful for his knowledge and hard work.

David Bailey

The one nobody else could fix

Not only a great auto mechanic, but really cares about his customers and their needs. He tells you honestly what you need for your car, doesn't try to oversell you, and works with you on what the most important issues are, instead of trying to tack on multiple unnecessary repairs.
