Mr Bruce,
There is a CSX4000 car (body & Frame) for sale on craigs list for $6000. It has even been spoken about on this site. If it does not sell at 6k I would think 7k would not have the desired market appeal.
FFR didn't sign a non-compete? I figured they were at least that savoy.
I have always felt there needs to be more Slabside variations to choose from. Even KMS has started in that direction with the comp body. There are too many 427 cars available at great pricing, even full roller glass CSX cars are now selling at 49k. If they up the production or drop $ further it will impact SPF, Mr Bolik, ERA, and all other quality kits.
Supply and demand FFR & SPF has the 427 body locked up in my opinion. Check ebay, there has to be more FFR and SPF's for sale than anything else. As the market gets softer more will feel the sqeeze. Slabside variations are only available from SAI or JCF in glass. KMS has metal offerings however sell the second house cause they are not really affordable to the masses.
I sound like a broken record right!
