F1BHP, I do not have the exact weights but I think that they could be just a touch lighter once the tyres are on, so overall not much change in weight.
Zoros, I'm doing this because it's how I do my projects, I like things to be just right and I don't cut corners. I might take it to shows and use it on the odd occasion as it's not my daily driver. It's not to sell and make money on it. But if I ever decide to than I'm sure the right person will appreciate what it is and what has gone into it.
I have seen some that have been, with all due respect, thrown together on an SL 500 base car and they get reasonable money. This is on a true AMG car so the pedigree is still there and I'm sure will reflect the the value accordingly.
I will post a few more pics later in daylight before it was transported to the trimmers for the next stage. Still some bits to finish off on the bodywork but nothing major. These will be done when it's back from the trimmers so as not to hold them up.
