After four or five weeks of searching, I have finally found a 156 - which I am picking up on Saturday.
It's a silver Y reg 2.0 Veloce manual, 38K on the clock and in really nice condition apart from a couple of minor marks on the bodywork which are being sorted before I get it. It drives superbly and seems really solid (no supension noises!). I'm buying it from Castle Motors in Sandhurst, who seem a really decent company.
Can't believe the standard of some of the 156's out there tho', some are really poor. I was especially disappointed by the cars I saw at Silvercheck and Car Giant. I nearly bought a Selespeed from Perry's in Amersham but decided that I really wanted a manual.
Will let you know how I get on. Can't wait to join the ranks of 156 drivers
