hey guys i'm looking to sell my silverado, wife just had hip surgury and can't get in it anymore and buy a 2002 tahoe lt with autoride. i'm new to tahoes never had one or drove one til the other night we test drove this one. it actually turned out to be our neighbors down the road, he traded for a new duramax. is there anything i need to be cautious of. i talked to him about it and he says he never had any problems with anything and he drove it everyday to work. it has 122000 miles on it and in in really good shape. i'm not really familiar with the auto ride. is there something i should check? i never seen him haul anything other than a lawnmower. is there anything i should look for????
