2007 Avalanche LT 13,500 miles
2002 Ford Explorer 95,000
2005 Impala 50,000
1989 Cavalier Z-24 convertiable 200,000
had a 1994 cavalier RS with a schoch over 300,000 on it before the body finally died and I just sent it off to finally retire.
I tend to put anywhere from 40,000-60,000 miles a year on my vehicles.
