Thanks for all the info regarding the dyno testing..
I read this minutes before the car was scheduled to be done and called and canceled that part of the test.

Turns out the ???valve??? seals are leaking oil onto the timing belt(which needs replacing anyway), the suspension is OE and definately shot (133Kmi), air conditioning compressor siezed up, vaccume likes are OE and needs replacing, brake pads are down to 5%, transmission fluid is burnt(even though it was drained and filled yearly) and... something to do with the steering is loose... cv joints? maybe...

needless to say, I think $4900 is too much. what do you think?

(paint was redone 2 yrs. ago and looks flawless, leather was professionally cleaned every yr and also looks flawless)
