I recently purchased a low miles (42,000), very well taken care of V8. Full service records, immaculate shape. In the few months I've owned it I've put 7000 miles on it and $11,000 in repairs into it.
If you cannot buy this car with a full CPO, platinum warranty, do not even think about it.
I have no idea what I was thinking buying this thing. It's wiped out a significant portion of my savings and I can hardly bear to see it sitting there in the driveway mocking me. If I were to sell it or trade it in at this point it would be at a steep loss.
Buying a Phaeton was probably the worst business decision I've made in my life so far.
