Older fibreglass 4xxx series cars are thought to be "superior", especially if you can find one that is pre-Hi-Tech (same manufacturer as Superformance, but not the same car). Especially the ones from HST. Mine was a carbon fiber HST car and I thought it was gorgeous. The quality of the body work was perfect.

Same for alloy body cars - early 4xxx alloy cars were built in house, starting at some point they were built by Kirkham (but were different from Kirkham), and at some point the alloy 4xxx/6xxx became just a Kirkham pulled off the line to get a CSX number.

Any of them will serve you well. I still say they were of the highest overall quality of all of the replicas.

Actually the alloy cars could be any variation of Kirkham supplied parts, from either Poland or Utah. On facebook, David was just getting some body and frames to send off to Africa from Utah to be made into CSX cars. He happened to have some in stock in Utah, but it seems body and frames could also be sent from Poland to Africa as well. David mentioned that he has also supplied complete rollers to Shelby, which probably go directly from Utah to Vegas. He supplies whatever they ask for at any given time.
