CL65 VS Continental Supersports
I've always found the old W140 S-Class Coupe to be a pretty neat looking car, but then as soon as it switched to the CL name plate, it got bland and lost a lot of its coolness for some reason. The second generation looked overstretched and awkward, but then the current generation just looks bland. It has a great interior, but it just doesn't have the appeal of an S-Class. The Continental, despite how common it may be is still more special.
E60 VS F10
Neither are my favorite generation of 5, particularly the E60. I sat in an early E60, a 525i, once and was pretty unimpressed. The materials felt hard and plasticy, and the interior design was a bit ugly. The F10 isn't my favorite either, but at least it's more comfortable and quiet than an E60, and looks a lot nicer. Plus I hear the F10 isn't that fun to drive, so who cares if most aren't manuals. I'm not a stick shift snob.
Beat VS Cappuccino VS AZ-1
The AZ-1 is overrated, the Cappuccino is meh, but the Beat is kind of neat. That rhymed. I'll take the neat Beat.
Ram VS Humvee
The Hummer. The Ram looks like it was a hack job, probably because it was.
Veneno VS Egoista
Neither, they're ugly!
E39 VS E60
The E39 is one of my favorite Fives, and the E60 isn't. The E39 has a V8 which is more appealing to me. It looks classier and has a better interior. It also sounds better, really.
A3 VS Mini Cooper S John Cooper Works of Awesome
Minis are fun to drive, look awesome, and handle great. The Audi is almost certainly more comfortable and probably sounds better (seriously, the Countryman S I drove sounded pretty bland) and is definitely more practical. But the Mini is a Mini, and I like Minis, so yeah.
