Welcome Ben,
What model of GT4 do you have - 165, 185 or 205 ? - Edited to see what you have got - Silly me

Funny you mention where you are, I'm down that way Wednesday stopping at Cirencester with work. PM me if you want to meet up.
As for meets, if you can make it, get yourself to JAE at wicksteed park in September. It does not matter if you don't drink (I don't), it is still a great laugh. (You can put some seriously silly thoughts into the chairmans head on how to attract people to the stand. For the results, see the picture album below..... Hopefully that works ok.)
