Definitely agree with the Merc, it has the elegance and attention to detail that makes it a genuinely beautiful car. Not a line out of place, and a classic style that gives it effortless cool, and doesn't make the driver look a bit of a plonker like a modern SL does.
The Roadrunner (or is it a Superbird?) isn't beautiful to me, which is strange considering it's based on the Charger which I'd agreed was a very elegant car. The nose is aesthetically (though not physically) blunt, and the spolilers and graphics are too OTT for me to consider them beautiful. However, seeing one doing 200mph on the banking at Daytona would give it the beauty it needs - it's a race car and that's it's perfect environment.
Again, certainly not saying you're wrong, as everyone has their own idea of beauty.
I'll throw another one into the mix - our first Ferrari in the thread.
1966 Ferrari 330 GTC
Now this was a difficult one. I already knew I loved the car, but one of the things I mentioned in the original post was colour. The 330 looks completely wrong in red, as do pretty much all front-engined Ferraris in my opinion. Mid engined Ferraris should be red or yellow, and the tourers should be chosen in metallic blue, silver or black. Classy colours to suit classy cars.
The 330 is an incredibly pretty car. Nobody would look more right driving such a beautiful Ferrari as a beautiful young woman. The shape of the car is tapered elegantly at both ends, the lights, tail ones especially, are small and discreet. All the lines are subtley accented in chrome, including the four fluted tail pipes.
The GTS spyder version is argueably even more beautiful, but I've always prefered coupes to soft-tops so the GTC it is.

No, really. Volvo 240 = pretty.
