Ok so here is something a little more serious ;)
They have already been mentioned so wont post more pictures but I would have the Maclaren F1 and a 22B both IMO iconic the F1 being a complete game changer for supercar thinking and the 22B a classic 2 door on steroids - nice :P
So here are my top 10 not including those two
What is better than a flat 4 - well x3 flat 4's - 1971/2 Ferrari 312B2 horizontal 12 - the sound is just awesome, I have got a plan for a replica based on a Testarrossa .....
...... the car is number 3 in this ad, always gives me goose bumps

Early GTR 1972 I believe - this would be a resto mod, original on the surface but blueprinted engine and modern running gear
An Eagle roadster - modern day E-Type, all of the style and performance plus working brakes, roadholding and steering. just beautiful
Bonkers rally car - Lancia Stratos, like a Metro 6r4 but way more style
I have a soft spot for nissans particularly Skylines this is the one I have always wanted and I am surprised that a Subaru even turned my head but it did the naughty minx
Think these are great - A brat - again it would be subject to a serious build with impreza engine and running gear conversion
Aston Martin DBS - V12, awesome styling -- nuff said
Ariel Atom V8 - V8 howl and an assault on the senses, trackday mayhem to ensue, new tyres please
Nascar / Euro Car - I drove one of these bad boys in the states - :D GOOD points similar to the V8 Atom its a complete assault on the senses, no traction control or servo brakes huge wall of awesome noise masses of torque, BAD points there was a yank in front controlling the speed you went and clearly thought Miss Daisy was behind him (overtaking was an immediate black flag!!) - Got to get one of my own to tear it up properly
De Tomaso Pantera - purely for the look - this is how I used to draw cars when I was a kid, I hope when / if I ever drive one it wont be a huge dissappointment
