How about this for an idea in relation to local cars and helping a good cause.
There are a great deal of Prestige, Classic, Vintage & Veteran vehicles in this area. I believe there is even a real Formula 1 car in Llandudno. How about having a display of all such cars, but don't link them neccessarily with any car club, on say, Llandudno Promenade on a Saturday. There could be Millions of pounds worth all lined up in the sunshine.
In the afternoon, possibly in either The Imperial or St Geoege's Hotel, there could be an auction of seats in each vehicle, which will take part in a rally on the Sunday, starting and finishing on the prom. People could bid to sit in the passenger seat, or Dickie seat, or maybe even get to drive their dream motor car on the rally. I'm sure there are many people who would pay several hundred pounds to ride in a ltd edition Ferari or Veteran Rolls Royce. On the Saturday night there could be a gala dinner for car owners etc. in one of the hotels with an auction of, well, whatever really.
On both days a collection could be made on the prom, with proceeds being split between St David's Hospice & Ty Gobaith Children's Respite Hospice. There's no reason why £30k plus couldn't be raised in all.
There's loads of people with magnificent cars from all eras in our area that I'm sure would help. Local garages could sponsor the event, have stands on the prom (I know it's all weather permitting, but if you don't try). Imagine a stream of magnificent cars rallying through all three towns nose to tail, what a sight. How about it's called "The Three Towns Hospice Car Rally". Something like that???
