Yes Car parts and accessories are important for a vehicle. Some car accessories available in automobile market are body kits, spoilers, sports mirrors, head and tail light covers, car hood shields,window visors, car covers, a sunroof, wiper blades, hood scoops, window graphics and wheel caps. These must be analyzed and inspected well if it is a used car or old car. Because if lot of repairs are there in the car parts, its not worth to buy a old car. So car valuation is more important for a vehicle.
