I have a Williams 1 and a 182 now as a daily car!
The Williams gets comments everytime I take it out and lately I've come out of shops to have people either taking pictures or having a look inside hehe. It's also mad as a sack of badgers both on road and track hoho.
The best thing I ever did with mine was get the wheel refurbished I think...oh and the ITB's.
Cambelt is relatively easy as there are no floating pulleys on these, it's just a case of having fun finding all those seized and rounded off bolts after years of never being touched!
The 182 is great too
