Hi Mate,
take a look at http://www.viczcar.com/forum/index.php/topic,4501.0.html ,there was a discussion on prices.
The 240's seem to range anywhere fro $1200.00 for basic shell and hinge-ables (with rust) to $30K+ for "restored".
If you want something decent to start with, minimal rust and complete,you'd be looking at at least $8,000-$10,000.
But hey, there's still bargains out there, just gotta be quick, with the money and no hesitation.
Good luck!
