355 What's the value hit for a car that's been in a minor accident?

I'm looking at this 355 GTB:

It's got two issues and is thus cheaper than others on the market:
1) it's Canadian spec, but has a US title. I'm not too concerned with that as it's 24 years old and I assume I should be able to fully federalize it at 25.
2) it's been in an accident. The rear bumper cover and engine cover were replaced. I've seen photos and the damage wasn't bad (appears to be a parking lot incident). Both pieces were replaced.

The fact that it's been in a fender bender doesn't concern me--if anything it makes me more comfortable with actually driving it as it's no longer a museum piece. But I do know it affects value greatly on these cars so I'd like to quantify how much. Any insight?

Thank you
