(AP) GENEVA - Some people go to auto shows because they're looking to buy a new car.
Others want to catch a glimpse of models they have no hope of ever driving, let alone owning.
Visitors at this year's Geneva Motor Show starting Thursday will get to see Lamborghini's Aventador J, a one-off topless design already sold to a European buyer for 2.5 million euro ($3.3 million).
Nissan's luxury brand Infiniti has no plans to part with the electric Emerg-E concept sports car it is showcasing.
And Italian design house Touring Superleggera made a 60th anniversary edition of the legendary Alfa Romeo Disco Volante for a wealthy buyer who already had every car he ever wanted.
Bugatti's Grand Vitesse is a rare supercar visitors can actually buy. Some 75 will be made and sold for upward of 1.6 million euro.
