Re: wheres the best place to go in the uk for a gta replica?
Try also Benalfa, alfaholics, aroc web site/magazine. Finally, there are a couple of 105 series coupe biased track days April / May at Castle Combe / Goodwood which attract a lot of that type of car ( mine included).
Check the Alfaholics / classicalfa web sites for details. If you were suitably located would be a good chance to come and look at a cross section and talk to owners / specialists. Maybe even pick up a bit of gossip about who's selling. I am pretty sure entry is free for spectators but ring the organisers, explain your interest and I am sure you would be welcome. You may even blag a ride.
