Another vote for the GTS colour scheme - did a quick search on car resale based on colour, and silver is currently topping the list in virtually every category from coupes to luxury sedans (it was 2nd place for SUVs) ...
Kelly Blue Book on Car Color and Resale ... of course the info doesn't necessarily apply to 40 year old supercars.
As for what I hear about the car - first show I took it to the guy at the 'gate' asked if it was a kit, haven't heard that since, and it's been 5+ years.
Do teens think the car is cool?...
A few months back a teenager with his girlfriend pulled up next to me at the lights and suggested a car swap (I forget what he was driving, a prelude or maybe a sunfire) ... I smiled and said no, then he offered to throw in the girlfriend - she was half hanging out the window for a better look at the car, but got back in and gave him a punch in the arm
I have the good fortune of having friends with both a Delorean and a Bricklin so when we go to shows, people can see the differences first hand - although I have come back from walking around the show to hear them telling people my car is a kit built on a Fiero, but I've been known to suggest Massey Ferguson might have had something to do with one of the other cars, and copious amounts of whisky went into the design and construction of t'other!
BTW, the story I've heard about the Bricklin tail lights is that the designer, Herb Grasse, was trying to work out what the tail lights should look like, and went outside, took the tail lights off his Pantera, and stuck them into the clay model of the Bricklin.
