This from the 'How many left site'?

If so I wouldn't take it as gospel.

On the FSOC there are many models and types of Sierra that are on the road or known to still exist but not MOT'd etc but NOT according to that site.

It's sad but, if someone buys a car its there's to either drive & enjoy, keep as an ornament or break and turn over some cash. Even if your a breaker.

At some point in the future they'll be lots of parts and not enough actual Cosworths. You'll have to start using regular Sapphires, but then the 'normal' Sierra enthusiast will say the exact same thing, which brings us to kit cars, how long before it all levels off and there is just a bunch of Cossie's, standard Sierra's and kit cars made from Sierra's?
