Jim, welcome aboard.
Not trying to drive you away (we love seven enthusiasts - car owners or not), but you can find alot of useful info at locostusa.com.
Definitely hang out here - you will find seven owners as a friendly bunch.
Also, try to arrange to get a ride in a variety of sevens to see what you like, either in terms of brand, or general characteristics - perhaps a bike engined car vs. a high strung 4 banger vs. a V8, etc... By their nature, sevens are not "seen one, seen them all" kind of cars...
:cheers:
