Getting your car appraised!!!

The last appraisal i had done cost me $250 and it was done by an independent guy with no affiliation to any insurance company,he did a very good job,checking everything on the car glass,stainless,bumpers,condition of paint,underside of car,interior,wanted to know exactely what was done to the motor/trans and rearend then took some very nice pictures of everything,i thought it was worth the money spent especially when i sold the car and everything i had done to it was documented with pictures....
