Add me to the list of, "Nope, not for me."
If I ever add another car to my stable, it will likely be a dead stock Ghia convertible. Or an air-cooled 911. Or a 911 SC cabrio. Again, stock. Those cars are just too pretty as-is to be mucking around with.
That way my wife has a cool car as well. (She's been hinting about wanting to learn to drive a stick shift. "Well, it's something I should really know how to do," she says. "Why didn't you have any interest until the day I drove home with a Porsche," I reply.
