While alive? Well, here they are (in chronological order). I can't give specifics about the earlier ones, because I was pretty young.

Dad:
-1980's Ford Ranger (I remember it most because there was a hole in the floor, where mud/dirt would come through the hole).
-1995 Ford F-150 (leased)
-1999 Ford F-150 XLT 4x4 (still has it)

Mom:
-1991 Isuzu Trooper 4x4 (very bad memories with that thing)
-1995 Dodge Caravan
-1998 Dodge Caravan SE
-2001 Dodge Caravan SE
-2004 Chevrolet Venture LS Ext.
-2001 Chevrolet Silverado LS 1500 4x4

All the Caravan's and the one Venture were leased. She is currently driving the Silverado.

Before I was born, I know my dad had a 1960's Pontiac GTO, a 1970's Pontiac Firebird, a 1960's Tempest and a few 1970's Ford trucks. My mom didn't get her first car until the late 1970's. It was a '71 Chevy (Impala I think). She described it as a beautiful car in a deep red. She said she loved it. In the early 1980's she let her brother use it. He got drunk, tried to drive, then proceeded to crash it into a parked truck. After that she had a Toyota Corolla wagon and a '89 F-150 XL (we still have that, but it doesn't run).
