Pricing guides offer a wholesale value and retail
value, but remember that these are only approximate figures and
your car's value will vary according to quality. Nice, clean
cars bring a premium. High mileage cars may bring even less than
the normal book deduction. Accessories increase the value of
your trade. Cars with power windows, air conditioning, CD players,
etc., are more easily sold and therefore bring a higher price
than "bare-bones" models.
