I've been a bit all over. My current fleet is a fox body GT, Turbo Miata, RHD Mitsubishi Mirage, Evo VI waiting to be imported, and Tom's old red toaster to haul junk around.
Variety is the spice of life. I've had some stuff that I really liked over the years. But there has been something in common when I look back. I've had a fresh air car in my fleet most of the time and Miatas have been in my fleet a lot. (T-Top or Drop Top) I like smaller cars which is fine because I don't have kids.
I've tried the 1 magic bullet and it never worked for me.
