Somebody backed into your car in a Whole Foods parking lot. Or you had a real accident and need structural work, not just a paint buff. The difference between shops matters a lot more than most people realize - insurers will push you toward their preferred shops, which saves them money, not necessarily you.
Quattro Auto Body in Bethesda and Silver Spring is the real deal. They do factory-certified repairs, use OEM parts (not the cheap aftermarket stuff that doesn't fit right), and they deal directly with your insurance company so you're not stuck in the middle. They document everything so your repair history is clean if you sell the car.
Get a written estimate that specifies OEM vs. aftermarket parts, and check if the shop is certified by your vehicle's manufacturer - it matters for structural repairs especially. Red flag: any shop that tells you to just skip filing an insurance claim and settle cash. Sometimes that's fine for tiny stuff, but for anything structural, you want it documented.
