I'd be much more interested in a $200 C-dale than a $700 Vitus 979. Nothing against the 979, but the C-dales are so versatile, and hold their value well.

Different ride qualities. The C-dale is stiff, whereas 979 frames can be very soft - "wet noodles" in larger sizes.

If you can't inspect or test ride the 979, pass. Not worth buying into problems.
