Not exactly what you are after...but you can pick up a decent 4th gen corvette for that kind of money. 1989 and up will have the ZF 6 speed as an option.
Not many cars you can get for the money these are going for right now that will deliver 0-60 in 5 seconds, top end of 150 or more...and let you pop the top off and cruise to and from work on nice days with the wind blowing in your hair. These cars with the all aluminum suspension, fiberglass springs...and massive brakes will handle corners...stop on a dime while blowing cold a/c. Parts are cheap for these cars.
Plus, I don't see them being worth a whole lot less than they are now...so when you are done with it you should be able to roll your dollars back out.
Here is a arrest me red 89 six speed for just under $10
