Hmm, not a lot is it ? Been looking at Mondeo ST220 3 litre V6's. Can pick up an 03 plate for about 6~6.5K. They can be tuned far easier than the KV6 and can be tuned to about 280bhp NA safely or turboed like they do for use in the Noble, well the sky's the limit !!
Anyway, sorry for hijacking this thread, just really disillusioned and peed off with my ZS at the moment
