I have the opportunity to buy a 1994 VW Jetta, gas engine. 67 k on the speedo, but an additional 160 k on the sticker provided to tell me how many km before the speedo was changed. It needs a heater core, heater fan motor, rear calibers, and the sunroof motor needs to be changed. All jobs done at home not through the dealership... So how much is this car worth??
