Whether you’re backing up in a parking lot or a pole gets in your way, fender benders happen.

If your car gets damaged, it can be frustrating getting those repairs done.

The first rule to follow is to get several estimates in writing. It’s not unusual for collision repair estimates to vary.

Most body shops use collision repair estimator software based on the rate insurance companies will pay for a repair. That means whether it’s a big dealership or a small body shop, the price tag shouldn’t be that different.

“They’re never going to be exactly the same, but if they’re within $50 or $100 versus $500 difference, then you know you’re in good shape,” George Mantzaris of Toyota Tampa Bay said.

A high estimate could signal a shop isn’t equipped to do the work.

“There’s a couple of shops in town that farm out the uni-body repair or the frame repair, because they don’t have the equipment,” Mantzaris said.

A low estimate can also signal a red flag. Watch out for a bait and switch scheme, refurbished or after-market parts, or leaving hidden damage unrepaired.

To protect yourself, look for certified technicians and a place that guarantees its work.

It’s also a good idea to trust your gut. You can usually tell if it feels right. Look for a clean, professional atmosphere. If a shop is really dirty, cluttered or disorganized, that might be a reflection of the kind of work they’ll do on your car.
