DENALI

I am looking hard at a 99 TA that has a new LS6 and auto trans just installed in it. He is asking 8k for it but i think i can getit for $5500. I am wanting the engine and trans for another project but would like to know what i might expect to recoup in parts from the rest of the car, it is in otherwise very nice condition. I am hoping to get a few ideas from you guys on different parts values since you know more about this generation car than i would. Here are some of the details on the car:

1999 Trans Am...white with 17inch WS6 wheels. New tires..
New LS6 Motor...motor is the ZO6 Corvette Motor with less than 2k miles...
Transmission rebuilt with upgraded clutches and shell...
Pacesetter Longtubes w/ matching 3in Y pipe
3:73 Richmond gears installed with girdle
Adjustable Shocks on front and rear...
Aftermarket rear control arms and drag bar.
BMR front sway bar...not currently installed
BMR Tower Brace also not currently installed...
After market seats in front



Thanks for your time.
