Pretty thorough site your club has, Mr. Bruce! Very nice cross section of Woody Americana.

Welcome to the SOC. Mike and Lane are right on.
Your question is a pretty big land mine, since members here are often very defensive of the cars they've spent so much time, effort and energy on. If you would like a windshield tour of what you might be getting yourself into, there's a whole folder under Makers (above) with good info inside.
I think you'll find that replica 356s are about like major league baseball clubs in a sense. I like Detroit, but the team's never really done much since 1985 -- if you follow the logic.
Baseball is a leisure sport. So are these cars; some take it lightly, and others memorize statistics back to the early days in Cooperstown.
Me, I like taking my glove to the park on a nice day.
There are more and more companies out there making kits and turnkeys of the Tub. This site's membership have an option to rate their own cars, and from time to time we get together to have a look at each others' projects. Every now and again you see something new, or you find that someone's made a modification you like and want to incorporate into your car.
Generally, there's no shortage of knowledge to exchange. If you look at the members' posts, there will usually be a link on the left of the post to the make and year of that person's car (mine, for instance, says 1994 other/unknown). Click it, and you'll see what they've done with a particular make -- then fire away with questions!
You can spend five grand on ebay and buy a VW pan-based wreck and fix it up, or you can spend upwards of $70K for a better-than-factory reporduction and have no worries from day one -- and it doesn't seem to be stratified by budget or manufacturer.
I would encourage you to have a look around under the Registry folder and see how folks have rated their builds or purchases, and then ask your questions more aimed more at what you specifically need out of a kit.
Better yet, have a look in the events folder under the Forum here and see if you can make a show!
I'd be happy to answer specific questions about my car for you, and I'm sure most of the others who post here regularly would do the same.
Again, welcome to the site!
