In UK

I only have one guess left. Anybody know this car?

What this car?

What actually was this car?

Spotted in Stockholm, Sweden.

What about it?

Never seen this before, no clue if it's rare or not. What is it?

What model is this BMW?

I found the Weiner-mobile! But in all seriousness, does anyone know whether this uses a stock frame or is fully custom?

What about it?

I saw this in Washington, D.C. (of course).

Seen at a car show in Orlando

My grandfather and friends

What about it?

What car is my grandfather riding in? He’s the one in the back with the awkward leg.

got no better pic, sorry.

When it started it had a very "american muscle" type purr to it. Any clues what the car is? maybe what could be under the hood?
