Notes:
1.) Suspension mods were when new, K04 since 85k.
2.) *I never paid for an extended warranty, VW sends me notices for coverage of common failures.
3.) A few times I was feeling lazy and got the dealer to quote prices for repairs. I ended up doing the work myself every single time as labor generally tripled the cost.
4.) Some of those are my fault and/or caused by mods. For example the wheel bearings I believe went from the extra force of the StopTech kit. I'm going to do the Right wheel bearing in another 1k or as I think it's starting to act up.
Would I buy the car again?
Yes! I see it sort of like a dog that won't behave. It can be annoying, but you somehow can't bring yourself to fault it because it's awesome. If I had to pay dealer prices for labor though, I probably would've skipped the mods.
