Like Dutch Leonard, I am fortunate enough to have my dream car.
It is a 2002 BMW Z3 that I purchased in 2007. I wanted one of these cars since the first model came out in 1996. I plan to lower the car by about 1.5inches in a couple of weeks since the aftermarket wheels increased the space between the tire and wheelwell and I don't like the look of it.
I have a topless pic in the galleries. Speaking of the galleries, people should post their rides in the car gallery!
I have a 2000 Nissan Pathfinder SUV that I love, as well.
When either of these cars die, I will promptly buy another, same model, same year (well, the Pathfinder I will actually get a 2001-2004 model, for a slightly bigger engine).
However, there are a LOT of different vehicles that I love, of all types, including the MINI and Jeep Wrangler (I would consider a Wrangler 4 door to replace the Pathfinder, actually).
Another long term favorite (since I was a small kid) is a Corvette Stringray.
