I have had a Q plate 3dr for over 3 yrs & its been the best cossie i've had,better than both of the saph's i had, its the one you mention above & its still only done 58k in total. never been pulled by the plod either, my mate is a traffic cop in Maidstone & told me that he won't pull a Q plate car over anymore than any other car as if its on a Q the police know its been checked over properly & put on a Q.
I only bought a 3dr on a Q as i couldn't see the sense in spending 7k on a 3dr i was going to rag around a track !
Keep thinking of selling mine as i don't use it much but it won't be that cheap as its a very good spec, will be at National Day in the infield parking.
