Have a friend who has, it's either 1/2 Mil or Mil on his 1990 Isuzu Trooper!I would get it fixed, but make sure you take it to a good shop that you trust for an estimate.
Fwiw, if it's been maintained, I don't know why you'd replace it. 190K isn't that many miles.
Not to hijack but do you know the website? I need a pre painted tailgate and bumper too.There are companies online where you can order pre-painted bumpers. I bought one for my wife's corolla once. Paint matched really well. I would think you're looking at $2k to get that fixed somewhere. Maybe more.
