if i had 10k like you do, id probably find the cheapest 2 seater i can, Say 5-7k- get it on the road, then slowly fix it up while i drive it.
or get a r32/3/4 skyline, but that's me. Ive had classics as my only car afew times now (datsun 1600-2602+2) and.. well.. the climate controlled, noiseless, odorless,bumpless, environment, with a nice stereo and fuel injected turbo (and almost 0 maintenance IF its a nissan) - is something that you do miss :-) but then again if you do have a modern car as your only car, The thrill of a light , fun, head turning classic will always be something desired!
hmmm, how about a 5k 240z (to be fixed up) and a 5k r32! awsome collection!
