I'm sure the whole Whitley Bay rally thing has been discussed in the past. Specifically about the merits of advertising it as vintage, but filling it full of modern stock.

Whatever the intentions of the organisers, if I saw a vintage rally advertised, I would expect to see vintage vehicles. 
Just as if I saw a Chinese restaurant advertised, I would expect Chinese food. Maybe apart from the odd exception to cater for other tastes, like omelette.
But that wouldn't be of interest to me. I can get omelette anywhere.

If the organisers were to take out the word vintage from their advertising, I reckon it is a quick fix to an annual problem.
