Reasonable price for a fender liner repair?

That's a reasonable price for four tires and an alignment, plus minor repair. The fender liner should only take 1/2 an hour to install. I would definitely look elsewhere.

 

1. Replace the fender liner yourself at a cost of $20 for an aftermarket part plus some of your time jacking up that corner of the car and removing the tire for access.

2. Go to the tire store and buy a new tire for $100 or whatever the price needs to be for a tire matching the other three.
3. Go to an alignment shop and pay $100 or less for an alignment.

 

Additionally, depending on how much tread you have left on the remaining three tires, you might consider replacing all four tires. If the tires are practically new then the one will probably be OK. If nothing else replace in pairs, the convention currently is to put the new tires on the back and your old tires up front.

If you have to replace them all, and you are a Costco member I definitely would recommend getting tires there. They have them on sale every month either Michelin or Bridgestone, currently Bridgestone is on sale.

 

Additionally, depending on how much tread you have left on the remaining three, you should consider replace in pairs or replace them all. The exception is that the remaining three are nearly new, as Patrick emphasized, "...a tire matching the other three". The current convention is to put the new tire(s) on the rear and the old tires up front.

If you are a Costco member Bridgestone tires are on sale through 4/17. Costco does not do alignments, though.

Don't know if people still do two wheel alignment, but insist on 4 wheel. Lastly, get the alignment as soon as you can after getting a new tire or tires, a bad alignment will shorten the life of a tire measurably.

 

What if you just need the liner and not the tire alignment?
