I haven't used them yet...the estimator/insurance company didn't take in to account how rare our cars are (insurance company's words), so I don't even have an estimate, yet, and they saw the car on Tuesday. The estimator, who said that she had been doing this basically half her life, wasn't that friendly/nice/informative. She said that it could be 10-12 days before it would be finished. I had sourced out all the parts I thought I would need, but they wouldn't use them. Looks like they may need my parts source after all.
