can anyone give me a estimate of how much it would cost to...

-buff the hairline scratches out of my car
-fix a minor dent
-replace the front and back bumpers

and i wanted to know if you could just paint over certain spots on the car rather than painting the whole car.

how much would this be if i went to a professional body shop?

 

If the dent is truly minor, I wouldn't let a body shop do it. Have a PDR (paintless dent repair) guy do it. For $75-$100, a good PDR guy will make a minor dent disappear with the need for repainting.

A good professional detail job that includes polishing out hairline scratches and swirls with a rotary buffer, shampooing rugs, cleaning plastics, etc. should cost around $200-$250.

I'm not sure about the bumper job. Price will vary based on the amount of damage underneath the plastic bumper cover.

Repainting a late model car lowers its resale value, so I wouldn't paint the entire car unless it was truly necessary.
