Nope. I was told that if the cams were off, there is so little
clearance for the valves that they'd go squish boom.
An inspection scope would be nice, but I don't think it will
help. Is it worth $300 to find out?

I was also told the stress the induced the pully/crank key
to (potentially) shear (all this is still speculation), would take
its toll on other parts.
I'm not sure I'd like the car with a 1.8T. Now that I've started
looking around, there's all kinds of nice stuff out there, some
nicer than others (from a 2001 Passat V6 to a 2000 A6 V8).
My gut says go with a generic commuter (like the Passat)
and save the 200 TQA for fun.
