I talked to a car salesman this morning and he told me that the 5000 Turbo Quattro only came with the CS option package. I looked up the average retail prices for the 5000 CS Turbo Quattro in the September NADA book. '86.........$7,050 '87.........$8,575 '88........$12,550 There is quite a jump in price from '87 to '88. Does anyone know why? Did this year get a torson diff and ABS?
