I found this aluminium cannondale for sale locally and I'm trying to ID the model to figure out if it's worth 150£
XT hubs, XTR 3x9 drive.

Decals are not original so difficult to identify it.
wWhat we can say : classic 3.0 frame with mud cutter stays ( ovoïd stays), 1” head and a collar for seat post. Sio it could be berween 1992 to 1994 bike, M500 or M600
give us the serial number on the left stay
