I work at a gmc dealer and we took some 02 RCSB's and installed Whipplechargers on the 5.3, Lowered 4/6, 17 " Torque Thrusts, Tinted windows, cowl hood, custom embroidered leather seats, and dual exhaust.
Now one of these trucks is for sale used at another dealer that is owned by the same dealer I work for. Thinking I could get a deal.
Whats it worth???? Oh its got 7500 miles

 

16K i'd guess. Dealer wouldn't have given someone real value for those things when they traded it in, so you shouldnt have to pay too much extra either. Now, if you can get them to cover the truck bumper to bumper with those mods, then you could make money by just having people who have whipples send you their blown motors for you to install in your truck and take in for service.

 

I was guessing around 20k. They sold it for around 38k new(ouch). I am going to try and find out what they have into it since it is the same owner as were i work. On the warranty, they said it is covered, but we just had a different truck in that we dealer installed the Whipple that had broken ring land on 5 and 7 and Gm said too bad. Our shop had to pay. i really want this truck but Im thinking I would have to pay 10k plus trade in my 100k 99 ECSB.
