Owners of older Volkswagen Jettas at what age and mileage would you expect to be the average lifespan mileage?

I'm sort of in the same boat as you, looking to buy a Jetta, Golf or ideally and Audi A4 with a 1.8T, year 2000-2003. I'm looking to stay under that 130,000km mark, but I too am wondering how long one can expect these cars to run.
