Sorry to here about your lexus and i would feel the same ?shop around it may not be as bad as you think, are you not protected on insurance, there is a place over here spray masters and would prob charge about £150/£200 and they do a good job, my mate had his lexus done on a bumper scuff and a ding on back wing, i think they charged £75 for the bumper scuff and £100 for the ding, hope this gives you some idea
