I attend several shows every year with my 1973 Capri. I do have a problem sometimes finding an appropriate class. The sports car class seems to be the best fit if there is one, but sometimes it is restricted to 2 seaters or ends up being 90% Corvettes.
The hot rod guys in general don't seem all that interested in my car, but on the other hand I am not really into street rods either unless they have flatheads or vintage speed equipment, so I have no problem with that. Although most of the cars are hot rods or musclecars, the owners are nice and friendly enough even though they are more into their own cars. I do find there is sometimes a lot of interest in my car with the other spectators at the show.
First, I am guaranteed to have the only one there and as they are very scarce these days, sometimes people that had one themselves or had friends/relatives with one get very excited and tell me "I never thought I would ever see one of these again!" and how much they liked it back then. It is fun to see people tell their kids that "Dad had one of those" or the younger crowd that had never seen a Euro Capri before and don't know what it is. I put a sign on in the window concerning the history of the Capri and find that people really like reading that kind of stuff on cars that are a little unusual.
Also just imagine a classic car show with 20 some old '64-'70 Mustangs and Shelbys. Many of these are high dollar perfect restorations way out of my league, but if you have the 10th best one, no matter how nice, it will get little attention since there are so many others on display. My Capri on the other hand, even if it is not nearly as valuable or collectable,is the only one there.
I do get real tired of every DJ at car shows constantly playing "At the Hop' and other 50's music all the time since most of the cars these days at shows like that are owned by guys who were not teenagers in that era.
I don't usually see much snobbery at the shows I attend. The only exception is a big aircooled VW show in Ypsilanti, Mi.I went to as a spectator. I saw one guy trailer in a mint 1977 Scirocco (that I had seen before) and they wouldn't let him bring it in since it was watercooled and I saw him driving out of there with it still on the trailer a few minutes later.
It wouldn't have harmed anything to just let him put on display even if it wasn't eligible for judging etc. It would have made a nice contrast with some of the later Karmann Ghias. My Capri by the way is listed in Readers Rides under Ford in this forum and under Mercury in the GRM forum if anyone is interested.
