yer i'm local, weird to find another forum member from norwich! have seen an exotica at budgens in harleston with some 18" dotz on it. And saw exact one to yours at aston garage in Long Stratton a few months back.
Mines really standard. Red trim round grill and thats about it at the moment. Should be whacking some OZ SuperT's on it soon and lowering it on eibachs.
I got it second hand from The AutoParc next to the Lexus/Volvo/Jag/Landrover dealership. Although I deal with Desira and the Alfashop for servicing/repairs.
