A technician arrives and repairs it

We come to the vehicle with the tools and the parts. You see the failed component before it is replaced, and you approve the work before it starts.

The tool system

One tool system, in every van.

We run Sonic Tools, and only Sonic Tools. That is not brand loyalty for its own sake; a mobile bay lives or dies on knowing exactly what is on board and exactly where it is.

Every tool has a shape cut for it

The trays are shadow foam. Each socket, ratchet and wrench sits in its own cut-out, so a gap in the foam is a missing tool and you can see it from across the drawer.

Nothing goes home under your hood

That matters more in a driveway than it does in a shop. The tray gets checked before the drawer shuts, which is the whole reason we work out of a system instead of a bucket.

The right size, not the nearest size

A full metric and imperial set on board means the fastener comes out instead of rounding off. A rounded fastener is what turns an hour into an afternoon, and you are the one who pays for the afternoon.

What it costs

The numbers, before you call.

The same terms in Conyers as anywhere else we work, and the same ones printed on the estimate you sign.

The visit
$65

Per trip, and it includes the first hour of diagnosis. It appears on your estimate under that name.

Labor
$125 / hour

Quoted from guide hours, not from a clock we are holding. Your estimate shows one combined figure for the job.

Warranty
30-day / 1,000-mile labor warranty

On labor we perform, from the date of the repair. Parts carry the manufacturer's own warranty.

Sales tax
7% on parts

Georgia sales tax applies to parts only, and it is itemised on the estimate before you accept it.

Customers

Reviews from across the metro area, not just Conyers. Same crew doing the work in each of them.

The mobile mechanic did a great job. He were professional, knowledgeable, and arrived when he said he would. They diagnosed the problem, explained everything clearly, and got the job done efficiently. I’m very satisfied with the service and would definitely recommend him to others.

Austin is the absolute best. I didn't know when hiring him that I would end up with a life long gear head friend! He really understands the intricacies of auto maintenance and worked hard to repair right the first time. He took extra care to make sure everything was resolved. Thank you

Questions

Before you let a stranger into the driveway.

Do you really come to me?

Yes. That is the whole service. We work at your home, your workplace or wherever the vehicle has stopped, across the Greater Atlanta Metro Area. The vehicle does not move and you do not sit in a waiting room.

A small number of jobs genuinely need a lift or a machine shop; if yours is one of them we tell you that up front rather than after we have arrived.

What does it cost to get someone out?

A visit carries a $65 trip fee, and that fee includes the first hour of diagnosis. It is not a separate call-out charge stacked on top of diagnosis time; it is the visit and the first hour together.

Anything beyond that is quoted in writing before we start, and you approve it before a bolt is turned.

Do I get a price before the work starts?

Always. You get a written estimate with the parts, the labor and the tax on it, and the work does not begin until you accept it. We do not invent repairs and we do not add line items you did not approve.

Is the work guaranteed?

30-day / 1,000-mile labor warranty on labor we perform, from the date of the repair. Parts carry the manufacturer's own warranty; we do not extend a separate parts warranty on top of it.

Parts you supply yourself are the exception. They carry no warranty of any kind and the labor warranty does not apply to a repair performed with them, because we cannot stand behind a component we did not source.

Can I supply my own parts?

You can, and we will fit them. Understand what changes: those parts carry no warranty, the labor warranty does not apply to that repair, and if the part turns out to be wrong or defective the labor to diagnose it, remove it and fit the correct one is billable.

What if I need to cancel?

Tell us as early as you can and it costs nothing. A cancellation less than an hour before the scheduled window carries an $85.00 late-cancellation fee, and every customer gets one courtesy pass before that is ever charged.

Which vehicles do you work on?

Most cars, light trucks and SUVs on the road in metro Atlanta, whatever the badge. Tell us the year, make and model when you request a quote and we will say plainly if yours is one we should not take on.

When can you come out?

24/7. Pick the day and the window that suit you when you request a quote and we confirm it with you directly.
