Hi Anita,
I should be seeing him in a couple of weeks when I get my car serviced. Can ask him about them then if you like.
I am only in Stourport so not too far from you if you wanted to hook up somewhere.
Suprised I have not seen your car around, in fact I don't see any zeds at all round my way. Tell a lie I did see a black one the other day but I believe your car is red from memory isn't it.
Maybe someone on here????
Anyhow let us Know.
Cheers,
Dean.
