Really boring looking 20 year old 7 series Volvo - er - with a B234F+T engine (translation, a custom built hybrid of the twin-cam and turbocharged engines). On youtube you can find some examples of Swedes who have got them out to very silly powers and speeds, one of over 530 BHP, an engine running on a stand with the exhaust pipes glowing allegedly turning out about 1,000bhp (!) and two kids in their homebrew with the speedo needle pointing vertically downwards which would translate to about 170mph, apparently on public roads!!

ALthough I'd also like a series 7 or series 9 Jag, or a 3.8 Mark II, or a D-type replica.

I have ridden in a Bentley Mulsanne turbo (not the full 400 bhp jobbie linked to above) and was underwhelmed. Not as much sheer grunt as I would have expected and the redline was a mere 4,500 revs.
