The Suburban is a TX Cadillac, s*** loads of those things all over the place! I say go for the Suburban! No troubles finding the parts you're going to need to fix it in the bone yards! All the Cruisers are still on the road so parts are harder to find for sure.
Just be sure to put a bumper sticker on the Burb so we know you're a Cruiser guy. That way we can pull you to the next service station!
All BS aside, hold out! I could pick up a 2002 Suburban tomorrow or hold out and buy a 1997 LX450 within a month for the same price. Biggest difference is the LX450 with still be worth something in 5 years, the Suburbans aren't much more then a seemingly good value and lot of car for the money!
