Great, thanks for the feedback....
Derik / Barry, I see where you guys are coming from and agree on the expensive to maintain bit...Barry, appreciate you pointing out items to look out for, its good knowledge to have beforehand...
This is entirely the reason why I intend to take it to the local Bentley dealership and have it checked out before I purchase the vehicle. I'm assuming their report on the health of the car and problems will help me understand the cost of repairs / parts and allow me to negotiate on the price as well...
