I have a 97 tahoe, as far as engine its strong as hell, each and every smog its extremely clean. suspension was messed with before i bought it and they were idiots so cant really speak on that. Think the worst thing my tahoe has ever seen is this damn BTL 18" i got in the back lol. beating the shit out of it. think im at 120k give or take some. not bad for the year it is.
