Just being having a look at potential Williams purchases and I've came across a Dimma Williams 1 that's for sale at the moment. I may be wrong but I think it's number 117.

As enthusiasts, what's everyone's thoughts on the Dimma? Is it a better proposition than the standard one, or is standard the way to go? I don't buy cars with a view to selling them shortly afterwards, but I don't want to buy a Dimma if it's going to be a white elephant that I'll struggle to find takers for later into the future.

Please help.
