That was too cheap Em!, Chassis number next to mine and a glimpse of yours in my build book IIRC.
Anyone looking for a S1 ? I know of one for sale by the widow of a deceased friend, Cream with red hood and interior, well sorted pampered car but not as cheap as Em's.
Sadly I think I know this car, it is very nice!
Shame to have yours sold Em, but you have to do what is best for the time and the Z4 is a great car.
Unfortunately no time to use mine currently, I really must get a spare set of wheels but availability and bank balance never allign!
