I've had my 00 Silverado since '05. It's a great truck. 210k miles and I've hardly had any problems with it.
I decided to fix a few little things a while back. I cleaned, polished, and waxed it. I replaced the grill, corner lights, and had the windows tinted. I need to polish the wheels better, but I want new ones soon anyway.
I tow a lot and the 1/2 ton has worked well enough, but I had a Duramax briefly in the past and I've always wanted another one. I picked up a '01 for $4000 with bad head gaskets. It has exhaust, a tuner, a fass lift pump, and a set of new snow tires, so I'd say it was a good deal.
I'm gonna overhaul the engine, re-upholster the seats, swap to the newer grill and bumper, paint it, and I bought wheels to put on it. I'll probably leave it stock height. My wife won't let me sell my 1/2 ton since it's what I drove while we were dating so it'll be more of a toy and I'll use the Duramax for hauling stuff.
