A B375 should rate somewhere around 110-115 depending on region. I agree they are sweet boats... Great lines, good cockpit and nice layout. A friend has an absolute cherry example...Do you know what this boat rates?
I came very, very close to buying a First 375:
Honestly, the biggest thing that turned me off was that stupid headliner. It's just such a silly thing to have to work so hard on.
I hope it works out for you. Cool boats.
