Need recommendation for C5 Corvette service in S. New Jersey

[Dave Rifkin]

I have a 2002 Z06 that I want to have some service performed on and could use some recommendations for a good service center who knows these cars and won't rip me off.

The car has a little over 68k miles on it and has a few things that should be checked out.

The oil pressure sending unit needs to be replaced (oil gauge is pegged; common problem)
The Active Suspension / Traction Control service lights come on
There seems to be a small leak somewhere as I have found drops of fluid under the car.

The suspension creaks; could be bushings maybe?
I have never had any brake work done so I would like to have them checked.

Kerbeck Chevrolet is nearby but, I am afraid to take it to a dealership for fear of being gouged.
