Prettiest cars, might not cover bikes, but I think Honda CBX of late 70's might be quite close to a top. If you like old GT-R, you might like what you hear in this: Update: There is another one, from road, where you can hear lower end too
not the most beautiful, and a love or hate car. I actually love it. shame its hated by so many people though
I think the '69 Camaro is nice, but the new one looks awesome. --- Post updated --- El Camino is also great.
Zaz 968? Never thinked of that, actually it's nice looking car! Although engine doesn't say same thing...
