What buyers say

Cracked a diesel gremlin two shops missed — 5★

Recurring limp-mode on my Duramax stumped a dealer and a chain shop. First Coast found a chafed harness in an afternoon. Solid diagnostics.

Clean used tractor for my hotshot rig — 5★

Bought a single-axle tractor exactly as listed. They handed over the service binder and let my mechanic crawl under it first.

Great work, plan for the wait — 4★

My Cummins injector job was done right at a fair number. They're busy, so I booked a week out — but they texted updates the whole time.

Keeps our landscape trucks rolling — 5★

We run four diesel dumps and these guys turn them around fast. Invoices are itemized and honest every single time.

Lift and tune done clean — 5★

Had a leveling kit and tune done on my F-250. Rides straight, no vibration, pulls way stronger. They clearly live and breathe diesel.

DOT inspection with no padding — 5★

Ran the box truck through and they only flagged the real items. No invented repairs to fatten the ticket.

Stood behind a used purchase — 4★

A sensor threw a code a week after I drove off. They covered it, no argument. Good folks.

Turbo swap woke the truck up — 5★

Turbo replacement plus a tune and my 2500 finally tows the gooseneck like it should. Worth every dollar.
