my '95 suburban has 235,000 and still going strong, my previous vehicle, an '86 suburban had 301,000 when i got rid of it, they drove it to chicago and back sortly after getting it (from north alabama). both have 350 engines and needed only general routine maintenance. i only traded it off because i had gotten the wife a newer model suburban, i took the '95 from her sinceit was 4WD and i originally got it for her so that i could inherit it later. i juat couldnt see keeping three suburbans along with two pickups, upkeep and insurance was getting out of hand. the chevy 250 was a tough engine, the newer suburban has the 325 engine, i hope its a good one too.
