Heh, well foolish or not, I bought a 2003 wagon. Mint. Or at least as mint as these things can get nowadays. In addition to the economic concerns of driving my GTI to high mileage, it just doesn't feel like the right tool for the job. That job being hauling me to work and back 120km/day (all highway), hauling mine and my kids hockey equipment, mountain bikes, groceries, etc.
So I bought a wagon with 114K kms on it (with a stack of service documentation going back to new, including recent timing belt), which I am confident can go another 400K without major surgery (there will be lots of minor surgeries, obviously). The GTI has 100K on it and based on my experience so far, as well as talking with my mechanic and various forums, I'm not sure I'd want to trust it much past 200K. For me that's 3 years.
Will it save me a bunch of money? Maybe. Maybe not. I am happy to do some minor wrenching myself on occasion (oil changes, brake pads, hoses, glow plugs, mounts, etc.) and I've got a very good independent VW/TDI guru who charges reasonable rates. In the meantime, I will eliminate a car payment (once I sell the GTI) and have a super practical vehicle that should be roadworthy for many years. And if in 2-3 years I change my mind, I will be able to sell the wagon for not much less than I paid for it (if any). It will still be a sought-after *very*low mileage vehicle if I sell it in 2 years with 175K kms on it.
Maybe it doesn't make sense to anybody else, but it feels right to me
