Getting 97 i30 serviced

[wulf69]

I got a 97 i39 with about 110k miles. I got the check engine light on, from a possible knock sensor, but had that replaced with no luck. been quoted to have both of my wheel assembly hubs in the rear for 840, i been told i need front strut work for 560. motor mounts for 880, i get strong vibrations while the car is idle from time to time.

New tires (i've had mich. tires on)

Everytime i try to hit the gas above 4 rpm real quick the car with start to clink like its coming from the under side, letting out a cloud of white smoke. quick acceleration kinda sucks on it now, i had spark plugs and general mainance a few weeks ago.

For the most part the car runs fine, just beat up.

Do those prices seem right? anyone know of a good infiniti service in charlotte? anything else i should have them look into?
