Apart from the usual things you look for when buying a used car (smoke, accident damage/sprayover, rough idle, funny sounds etc.) look for this in particular.
Listen carefully to the 240's engine while it's running. If you hear a rattle/scrape from the front part of the motor, a timing chain replacement is probably in your near future ($800-$1000 with labor).
Other than that, there aren't many intrinsic issues with them, they are pretty solid.
EDIT: I like your handle, BRONZE! Gonna git you!
