The R34 has always spoken to me. Love the look of that car.
Over the last couple of years I've hit full empty-nester mode and I think I'd change up my lottery garage from what I listed earlier. There wouldn't be one car, because there is never a single vehicle that would effectively meet my needs. Right tool for the right job.
My Daily: The Audi RS6 Avant or RS7. This would be my bad weather daily, multi-passenger hauler car, and comfy road trip car.
Wife's Daily: Current Gen Acura MDX in top spec. Wife loves this car, and it slots in nicely for being a 7 passenger hauler without going with a massive land yacht like a Tahoe.
Fun Daily/all-arounder: Porsche 911 Turbo. I've wanted one since I was in grade school. Black with bronze wheels. I've probably end up driving it a lot more than the Audi, because...well, it's awesome and fun!
Tack Car: My current BRZ. Strip it, maybe cage it, put functional aero on it, mod the heck out of the suspension and engine. While not powerful, its an excellent autocross and track car.
Utility hauler: Some low cost mid-size crew cab truck like a Colorado, Ranger, Tacoma, or Frontier. Nothing fancy, just a good bed and 4x4 to haul garden supplies, furniture, lumber, kayak's, fishing gear, etc. This vehcile would likely sit for long periods of time unused, but good to have when needed. Some people put a sports car on a battery tender, I'd have a truck on a battery tender.
