to maintain the Bentley source V8 would be? (I was hoping it was the BMW V12 like in current models, but it's sadly not). Good news is, is that the transmission is basic General Motors, so they are a dime a dozen.
It also means that if your Bentley motor fails and you don't want to pay the $$ for upkeep, I'm pretty sure a GM small block swap would be cake. Heck, a modern LS might be plug-and-play easy.
You may have found the diamond in the Rough, TheLost. An exotic that in the end might actually be pretty cost effective to maintain...
