Search is my friend. The latest screwball idea I have is selling the A3 and picking up a used FJ for off-road/camping duty, and finding a cheap Miata for occasional track days. A quick search indicates that there are modded ones under $5K around. Basically I don't care about the paint, etc, just good mechanicals.
Well, and a matching purse of course...
Can you tow a Miata without a trailer (ie with tow bar)?
