Suppose I am Biased really as I own a MGB GT, and had countless MGB's.
Erm MK1 as I have never driven or owned one.
Hard choice though.
Ahh MG owners tend to be up their own arse for some reason too, dont know why because the MGB GT is just a Morris Oxford Coupe LOL.
Ahh I aint one of those type of MG owners either!
