My daughter is considering buying a used 1995 VW.

We don't get involved with costs here because there's way too many variables including the engine size which you didn't list. In general PVC hoses are pretty insignificant and take only half a minute to pop on, but it's hard to say with Volkswagens. My '88 Grand Caravan uses a specially insulated hose that's readily available in any salvage yard, but new they used to be rather expensive at four bucks.

There's a reason you don't see many Volkswagens on the road. Be prepared to spend double for repairs what you'd pay for almost any other common brand, other than BMW and Jaguar.

Engine size?
