Ugh,Normally I try to avoid multi-piece bodies like the plague.
But I have built a few. The 59 Ford retractable wasn't too bad,and the top actually worked.
Right now,I have an old Pyro VW Beetle half assembled-for the past 2 years. And the Lincoln Futura. Not sure if that will ever get built.
You know,looking at the first pictures of the ancient hot rods- I have never built one of those. I might try an straight out of the box build one of these days.
