A couple of cars I would kill to have, have been mentioned in here(Magic School Bus, Dick Mobile, Bucatti Veyron, the Corvette, Mustang) But theirs just a fe more I'd like to mention..
The Mclaren F1!

That's a Koenigsegg CCX, not a McLaren F1.
The CCX was, on it's original release, almost impossible to drive due to it's lack of a spoiler, meaning it had no down force.
On Top Gear, they tested the original CCX and even the Stig couldn't control it well enough to get a good lap time (he crashed it and wedged a tyre into the front grille).
After adding a spoiler and tweaking the chassis, it managed to set the fastest lap time until the Gumpert Apollo managed to beat it (but the Apollo makes people hate their eyes).
The McLaren F1 is far more expensive than the Veyron at around £2million (today's value), it has a gold lined engine bay and in a straight drag race, it'll out accelerate the Veyron, though it's top speed is a fair bit lower.
The Veyron also has more kit in it and it doesn't have that stupid driving position.
As for cars I'd have:
Aston Martin DB9 or V12 Vantage: If you think they're ugly, you have no soul.
Pagani Zonda Cinq: Imagine, "My car is made of carbodium!"... Seriously, carbon fibre isn't nearly strong or expensive enough, so they made a new material :/
Tesla Roadster: Based off of the Lotus Elise, but with different body work (like the VX220) and a battery powered motor that allows it to outrun the Elise with ease despite being quite a bit heavier.
Honda FCX: Seriously, screw electric cars, screw Prius'... Hydrogen makes more sense.
If you live in a country that relies on fossil fuel or nuclear power plants, electric cars are going to rely on those.
With hydrogen, you still need power plants to power the machinery required to split hydrogen from oxygen (hydrogen is most commonly available as water when mixed with oxygen), but because you can produce and transport hydrogen from anywhere, you could build a solar powered refinery in, say, the Nevada desert, meaning little or no reliance on fossil fuels or nuclear power... Plus, it's piss off oil producing countries that use their profits to build islands and such :]
GM Hy-Wire: I know GM is a failure and I know 90% of American cars suck, but the general idea was pretty intriguing.
The idea of having a car that can be easily converted from one kind car to another appealed to me as it'd mean you wouldn't be stuck with one car (though performance would remain largely unchanged between the different bodies due to them using the same power plant).
Also, Rockman, the Ford GT is pretty unreliable, so I doubt it'd even get five miles before something broke on it (it is pretty thirsty though due to it's engine being from the Ford Lightning pickup).
You could also mention the fact that the doors make it virtually impossible to park in a car park as they cut into the roof (not a problem on the GT40 as it wasn't built for such things, but the Ford GT is a normal road car).
As for the Jag in your post, I really hope that's a Knowles Wilkins or similar or it'll definitely implode, explode or fall to bits :/
