  • Daily to performance The commuter and the project car, held to one standard.

A repair shop that talks to you like a person.

Most people walk into a shop bracing for the runaround. Iron Mountain Mechanical and Performance was built to be the opposite. You get a clear read on what is actually wrong, what it will take to fix it, and what can wait. No padded invoices, no mystery line items.

We work on the daily driver and the project car alike. That means careful computer diagnostics, the maintenance that keeps a vehicle out of the shop, and the performance work that makes it fun to drive again. Same garage, same standard.

02 / What we do

Four ways we keep you on the road.

  1. Computer diagnostics

    A check-engine light is a symptom, not an answer. We pull the codes, test the systems, and find the real cause before anyone touches a wrench.

    Find it first

  2. Oil & scheduled maintenance

    Oil changes, fluids, filters, and the manufacturer-interval service that quietly prevents the expensive repairs down the road.

    Stay ahead

  3. General auto repair

    Brakes, suspension, drivability, the noise you cannot quite describe. We fix what is broken and tell you straight what is not.

    Done right

  4. Performance upgrades

    It is in the name. More power, better handling, and the tuning to back it up, dialed in for how you actually drive.

    More out of it
