Isetta

A microcar made by Iso Autoveicoli and then produced under license by BMW in 1955-62. It had a tiny 300 cc 1 cylinder engine which made 14 PS and could take the car to 85 km/h, and it only weighed 353 kg. Its unconventional bubble shape popularized the term "bubble car" to refer to cars like it. It also had a single door placed at the front and the engine was behind the seats. In more recent times it has gained a cult following due to its funny looks and for being so radically different from anything ever seen before or since.

Guy 1: Hey, is that a BMW Isetta!?!?!?
Guy 2: Yes it is. I bought it because it is the most based car ever made.
Guy 1: I agree, it is so good it is literally God.
Guy 2: Do you want to join the Isetta Church?
Guy 1: Hell yeah.
