No one in their right mind would touch one out of an 800! Or a kia sedona. However, after that they got it sorted and it was fine. Best one is apparently the 2.5 litre version from the 75 with a turbo charger. Didnt make many though so bit hard to lay your hands on.webmaster said:However the KV6 engines do not blow headgaskets
You've not seen the version in the 800 then Head gasket failure roughly every 30-40k miles.
A KV6 sounds like a V12 with a good exhaust IMHO.
