i bought it too and then regretted it, wrestled w/the idea of keeping it vs. returning it and getting most of the money back. i decided to cancel it and I got about 85% of what I originally paid for it. never should have got it, was bad judgement the day i bought the car.
mine was good for 7 yrs too, something like that, 75k miles. me having the added 2 year/24k mile CPO extended warranty too was a factor for me. basically i have close to a bumper to bumper warranty up to almost 60k miles and powertrain up to 60k. so im taking a gamble that nothing insane will happen to my car in between 60k - 75k. if it does, im gambling it doesn't cost as much to fix as my extended warranty was to buy. also, when i bought the extended warranty it was rolled into my car payment, so i was essentially paying interest on it, which is retarded.
lastly, i am stage 1, and i think the extended warranty is through first extended, a third party, not VW, so i could potentially run into problems with them covering problems blamed on tune. there is a section in the fine print on the reverse of the first extended paperwork talking about how any engine modifications resulting in denial of coverage.
right after i was refunded the extended warranty balance, well not refunded, it went to the lien holder to paying down my loan, i went out the next week and bought stage 1. so it all works out...
