I like a lot of different cars, but over the years my specific interests have driven me towards two vehicle lines:

SIA - I have always liked Subaru Legacy wagons, the crossover wagon of the 90s before the term "crossover" was even coined. Subaru set up Legacy production at Subaru of Indiana Automtive at Lafayette in 1989, from the beginning, and progressed the lineup from there. Subaru no longer sells the Legacy wagon in the United States, so the crossover is the new wagon. My new daily driver, the Subaru Tribeca, is an example of where we are now in wagon/crossover design.
GM Full Size - We only knew GM products in my family growing up, and when my wife brought the 2003 Chevrolet Tahoe into the family I should have known the trend would continue. From there we added a 1993 Cadillac Fleetwood and a 1998 Chevrolet K1500 for full representation of the GM full size line out of the Arlington assembly plant.
