Looks like this initiative died, which is a real shame.
I think that Vauxhall finally woke up to the differences with Ford, who had a much closer relationship with at least the 'official' clubs and put a little more support into the support of enthusiasts.
Vauxhall has for a number of years opened its doors to things like the Heritage Centre in Luton and provided the venue free of charge each year to clubs for an annual meeting next to the factory. Granted, no factory tours, but they produce vans these days at Luton and Ellesmere Port is the place to go in the UK for cars. EP is also opening its doors more now to owners to celebrate anniversaries at the factory their cars were built.
Lots of differences between Lotus and Vauxhall though, and perfectly understandable that scale of production probably is reflected in the budgets that the PR folks have to burn on promotion of the brand to enthusiasts like us. Surely by nurturing our enthusiasm in the cheap seats, they might work up some conversions to new Lotus model ownership as well as fuelling enthusiasm in the models that earned Lotus it's name and provenance.
Is there any single body that incorporates and represents all of the various clubs to act as an interface with the factory so that perhaps that relationship can be worked on? Have a look at the VBOA
www.vboa.org.uk for an example.
All that said, I thoroughly enjoyed the day out at Brands and will be up for similar opportunities to meet up elsewhere. It's not all bad.
