Ah ok, also in italy we have a lot of circuits "for kart", high speed and loong corners, but a lot of tracks is techincal. RRz is better than RR in all circuits

Here "the market" is a little stationary...u can easy find a lot of italian chassis at 1/4 or real price. For example u can find RRz 2012 without engine at 950 euro (680 £) or Rrz 09 without engine at about 750-800 (540 £)...and i think is not too much for Brits.
Usually in England the salaries are higher than in Italy and the change help u a lot :P I think u can easy buy chassis here for try there. =)
Just my opinion
