There should not be a problem with letting Next Generation Old Skool Fords onto the the forum and having their own sections, after all there are quite a few people on this forum with donor engines etc from later models (i.e. Cosworth engines EFI pinto's and even the Zetec from even newer models), do we start restricting these owners too because their cars are not within the spirit of old skool!!!, and also what about non ford engined conversions, i.e. Vauxhall redtop and Toyota engines do we ban these all together!!!. When I have arranged meets ups in the past I have always opened it up to the local RS Clubs and other Ford Clubs in the area. I mean after all what harm would come of it, you are not being held at gun point to own or drive one, these cars have their place within Ford's history they might not be what you like but I expect that some people that own newer cars might not like older ones.
I really don't think we will be over run with Mk3 Escort and Sierra owners, as the tin worm has claimed a lot of them (Ford did not seem to use their best quality metal in the 80's), and a lot of the Cosworth Sierra's either had their engines liberated for use in older cars or ended up in the crusher due to losing arguments with trees etc.
Don't fear change, embrace it, if we didn't change once in a while we would still be living in caves banging rocks together.
I'll stop now rant over.
