Allrighty, here goes for my dream garage made of cardboard and surrounded with Hedgehog-inhibiting material (also know as anti-slap paint):
1) Porsche 911 of some kind. Would pick LBs brain to find out more, as I don't know enough to pick a specific year/style
2) Nissan 370Z Nismo
3) Mazda RX8 with mods (I don't care if it might leak oil and whatnot, it would be a blast to drive)
4) Keeping the 2011 Honda Odyssey, since I still gotta haul kids (and hey, it's nice)
