No problem I'm often over the North West or we could meet up at one of the GTG and you can have a drive in mine see what you think. To be fair my input was building all the bits back together which is the easy bit

but I can put you in touch with the same people I spoke to when I started mine who will tell you honestly what can and cant be done my advice is to really do your homework on what you want then talk to the people and then decide if it is worth spending the money.
The main driver for doing mine was I wanted the same power as a CLK430 but did not want the autobox so the choice was selling mine and buying a 430 and converting it to a manual or trying to get my 230k to a 430 bhp. I already had a good starting point as mine had the Brabus K1 tuning kit on when I bought it so was 231 bhp compared to the standard 197 bhp.
Happy to chat though over a beer and sandwich anytime you want
