1999 GMC Sierra 1500 Unknown

I have a red 1999 and a half z71 which is the round body style not the square one with 206k miles that i want to trade for a 1996 or newer toyota 4x4 extended cab. I have cash to throw in if your truck is worth it. My truck has 3 inches of body lift tortion keys to lift the front and 35 in mud tires with 50 to 75 percent tred left. It is extended cab with the 3rd door. Dual exhaust that sounds amazing. It is nearly a daily thing for somebody to come up to me and tell me how good my truck sounds and looks. Has after market door speakers and radio with sub and amp wires already ran ready to hook up. New U joints, CV axle, driver window motor and tracks. The problems with the truck is that it has some dents on the passanger side on the bed, the shocks squeek a little bit and theres a rust spot at the bottom of the cab on the drivers side. It is about an inch tall and 5 inches long but has not got any bigger since ive had the truck which has been over 2 years.
