What to do...
I have a 2011 Si with 286k on the clock. I bought it new, I drove for a living so it's mainly highway miles. It has original everything. Clutch, freon, coolant, starter... the thing just never quit. I changed the oil religiously with Mobil 1 its whole life. Its been parked for the last 2-3 years. Is the Z3 still in high demand? Do you think it's worth more together or is it better to part the thing out?
