I thought the 6.75 OHV V8 was bullet proof. The parts might be expensive the the engine is dead simple.
I'm not saying it's a
bad car, but it's British so there
will be issues. Here is a review from a Bentley owner's website:
I recently bought an 2003 Arnage. The best info I got was from an indepedent shop I went to that specializes in Bentleys and RR's. He did a ppi on a 2000 that I was looking for and provided great info on them. Basically he said stay away from the 99-01s due to
head gasket issues. If it hasnt had one done recently it will soon.
An updated twin turbo power plant was put in the 2002's that is more reliable and econimical (10mpg, lol).
They eat batteries so put in dry cells and they suffer from
suspension issues so make sure to get that checked out. Also
have the turbos checked out for leaks in the waste gates. More so on the single turbo versions.
To answer your question the green label had the old bmw motor. The red label has the 6.75 bentley motor. The bmw is less powerful.
