Columbia vs C&C
I had a similar choice... Columbia 32 or C&C 30 mk1. Colimbia was a bit newer and bigger. C&C was a few years older, but well kept.
Surveror said not to even bother surveying the columbia if my other choice was a C&C. His reasons where quality of build and sailing ability of the C&C. I remember him saying something like..."the columbia is not a bad boat, but...
Finally I asked him "if it was your son looking at boats what would you tell him?"
He said "oh no doubt, go with the C&C survey first".
Best of luck,
