Welcome. Not sure that the mk2 was in limited enough numbers to make it rare enough for a lot of years. For value we need a desire and scarcity...but the RS brand has always done well at some point.

I think the antiques road show said that to create modern value you need something that was disposable...like a Harrods China set, loads of people buy them, break them and then throw away...wait a bit and nostalgia builds and the want comes back' just like Raleigh choppers and 205 gtis.
