Hi,
"You pays your money you takes ya choice".
If you have had 4 8v's then maybe it is time for a change. I have had a 16v in the past and driven a mate's 8v a fair bit. The problem these days with the 16v is that you need to install one of those k-star box of tricks if you want to run on unleaded.
Personally, I would go for a very late model 8v with power steering and as many options as possible.
