Yeah,the Autobahnstormers. I joined when I had a Carlton GSI,mainly for the trade club discount at VX dealers and found the forum friendly and informative.A lot of the members own Lotus Carlton/Omegas and discuss the finer points of Lotus ownership at great length,which is very nice,if you can afford a £15K Sunday toy!
A lot of members run Omegas as everyday cars though,and their knowledge of the cars is quite extensive and although the members gallery seems to favour the earlier cars ie Carltons,Monzas, lotuses(Loti?)and the like,there are lots of cherished meegas owned by members.
The club predates web based car clubs by many years,and to be fair, was formed at a time when membership fees were the norm.Mind you you do get four magazines a year and a sticker!
