The M3 and M5 used to be high on my list, but the recent trend of interiors for them are utterly abysmal. You might as well be in a Toyota. The styling tweaks have really blanded the 3 and 5 series a whole lot too.
I yearn someday to own a hybrid. Prius? I don’t care, any kind that is safe and gives great mileage. Cars are just transportation to me. They all look the same to me, and I am unimpressed to gaze upon some fabulous ‘classic’ or something that goes like a rocket ship. ( Despite car commercials showing some hunk of metal merrily hurling down a totally empty highway, there’s no place to drive the things,)…If I had to pick a ‘real’ car, I’d pick a Volvo. And if my first car, a Cutlass Supreme, was resurrected from the junkyard, I wouldn’t say no! THAT was a nice ride.
1968 Plymouth GTX convertible with the optional 426 hemi.
You, Madam, have amazingly good taste. This is my list too, though I would add that the Lotus would be in some incredibly, obnoxiously bright shade of yellow or orange.
For a daily driver, probably an Audi A8, something with big horsepower, all wheel drive, but somewhat understated.
I have always wanted a Porsche 911. I’ll take the Turbo Cabriolet. I might want to keep my BMW all wheel drive for winter driving, though.
It’s between a 1987 Buick Grand National GNX or a 2009 Nissan GT-R.
As a daily driver, I’d go with the Nissan.
EV1, if they haven’t all been crushed.
It’s been the Porsche 959 since I was 4, and it will stay that way forever. Not that I’ll ever actually own one. 
I have this wierd problem: I never seem to be able to sell cars. So the stable currently has five. From utilitarian, to audacious, to hot and high-strung to hot and well-behaved, to hot and will run in any weather.
So I guess I’d pick the Tesla sedan…
mostly for the touch-screen
Money being no object doesn’t free me up entirely, I’d still have moral and environmental objections to vehicles I might otherwise covet. If it’s just money, I’d like to test drive some vintage Rolls and see how I liked them. I’m also partial to some of the 60’s and 70’s Mercs. But given an unlimited budget, I’d have to do a lot of testing, because I have no idea what I might like, not having tried.
If there were also no moral, practical or environmental constraints, we’d be looking at light military vehicles, and pimped versions thereof. 
Sign me up as chauffeur. After watching a Top Gear cover it, all other cars pale by comparison.
I would need something that would carry two Cellos in their cases and also both of the Cellists. I would also need something that would carry construction materials. So I pretty much have to have a four door truck with a rack. Golly. I that’s what I drive.
I too will go with the Veyron as the personally most desired production car.
A one of a kind? There were 36 of this general body type made, but I think this is one of a kind: http://www.carsbase.com/photo/photo_full.php?id=21666 Used to be the Harrah collection.
Price no object?
I’ve always liked the idea of having a VW beetle – one of the old ones.
With an engine from a Lincoln Continental in it.
Porsche 917/30
Bugatti Veyronv. Porsche 917/30
0 – 100 km/h in 2.46 s v. 0- 100 km/h in 2.5 s
Top speed 253.5 mph v. 254 mph
So yes, they are similar, but here’s the single most important difference: the Bugatti Veyron comfortably holds both you and your sweetheart, whereas with the Porsche 917/30, your honey has to squeeze underneath the rear deck and cling to the suspension for deal life, which aside from severely limiting the possibility of post excursion activities with your honey, also limits the performance of the Porsche 917/30 to well below that of the Bugatti Veyron.
Plus, I doubt the 917/30 is anything close to street legal in its raw form.
Those performance figures are for the “vanilla” 917K. The 917/30 was the turbocharged Can-Am version, which produced a hair under 1600 brake horsepower in qualifying trim.
0-100 km/h (62 mph) in 2 seconds.
