How much would it cost to repair a dent

That is a question for any body shop. We do not get involved with costs here, and we are not body experts. Plus, there' are too many unknown variables. At the body shop, their labor rates make it impractical to try to repair the trunk lid. They will simply replace it with a new one or one from a salvage yard, if they can find one. If a plastic bumper cover is involved, the amount of damage to it will determine if it is a better deal for you if they replace it or try to repair it. Either way, the entire part will be painted, and paint for cars is horribly expensive. They will also need to add an additive that makes the paint flexible when it's used on plastic or rubber parts.

Visit any body shop and they will check for mechanical damage behind the parts, then they will write up an estimate for repairs. Replacing a part will be listed in their crash guides with the required number of hours the job is supposed to take. Almost all body shops bill their labor time by adding up those listed times, called "flat rate", so they will all charge the same amount of time for the same repair. The difference will be in the shop's hourly labor charge and in whether they want to replace parts or try to repair them. They know it is usually a better deal for you if they replace parts.

Also be aware the lowest-cost estimate is not always the best value. They could employ less-experienced people or they might use lower-quality materials. Some shops provide the lowest possible estimate, then surprise you later with the additional things they should have found right away. Some shops include extra charges in their estimates to cover those unknown things so they don't have to surprise you later after they find them. They are hoping they do not run into any of those surprises and they can hand you a final bill that's lower than their estimate.

When you compare estimates from multiple shops, compare which parts they are going to repair the same way, meaning if one is going to replace a part and another shop is going to repair it, you have to look at the total cost of labor and material for just that part. If they are both proposing to do the same repair procedure for a part, they should have the same number of hours listed for it.

It will go into the history and you should not get any further responses. Don't respond and it will not come up on our active board.
