Hi all, just came across these on Gumtree, both at the Ainsdale Car Centre Southport. The Z3 is a 1999 1.8 66k in regulation Topaz (like mine) with a blue interior, the Z4 is a 2012 2.0L manual probably about 70k, on a short MOT in grey. Just Google the dealer name. Good luck to anybody interested. Chris
