Impossibly sleek, deliciously overpowered and totally out of financial reach, the latest concept cars made their debut at the British International Motor Show.
Like the Rolls Royce E101 EX, replete with crystal glass Spirit of Ecstasy mascot and LED lights embedded in the leather headlining.
Although Rolls-Royce's owner BMW has said there are no firm plans to put the elegant two-door model into production, group chairman Helmut Panke hinted that design elements, if not the complete car, might see the light of day.
"The E101 EX symbolises a potential direction that a coupe, based on a Rolls-Royce Phantom could look like," Mr Panke said.
"The reaction to the car has been nothing less than enthusiastic."
A decision to move into manufacturing would depend largely on potential demand, particularly in Britain which is one of the most important markets for Rolls-Royce.
Another concept car likely to have the super-rich clam-ouring for it to be put into production was the four-door Aston Martin Rapide.
Sharing a family resemblance to the current DB9, Vantage V8 and Vanquish, the Rapide boasts such innovations as an electro chromatic roof which can change from clear to opaque - and back again - at the touch of a button.
Boasting a tweaked V12 version of the DB9's engine, the Rapide, with about 480 bhp on tap, would undoubtedly live up to its name should it ever make it onto the roads.
Aston Martin, now part of Ford, said it would take 36 months to get into production, a tantalising statistic for fans of the iconic British car brand.
But one car that definitely will never move beyond the concept stage is the 907 from Peugeot.
Designed as a means to showcase research and development capabilities, the low-slung V12, 6.0 litre, 500 bhp coupe has the looks to make it a sales success, if not the badge cachet.
An integral glass roof flows seamlessly from windscreen to back window and four short exhausts exit just ahead of the passenger doors.
While many concept cars have design cues that filter into production models, one of the most striking of the 907 - a glazed panel in the bonnet revealing twelve intake trumpets reminiscent of a fairground organ - are unlikely to be seen in any Peugeot showroom any time soon.
