Yes it is. All I know is that people can turn into cars? I only know that because of gifs that have been posted in past fighting game threads.
While turning into a car probably isn't even an ability I'd consider strange in Jojo, I think you were probably just misinterpreting what was going on due to a lack of context.
Anyways, the series is a long-running (and still ongoing) manga and has had several anime and video game adaptations. A lot of people were first exposed to it by the amazing
Capcom fighting games. It's a very popular and influential series - there's quite a few well-known fighting game characters whose designs were based off those from Jojo. Guile, Benimaru, Rose to name a few.
There's 8 parts to the manga - while there is a distinct timeline and many connections between the parts, each part has a different main character and (mostly) different cast. It's called 'Jojo's bizarre adventure' because the main character's name can be shortened to 'Jojo', for example
Joseph
Joestar or
Jotaro Ku
jo.
Parts 1 and 2 can be summed up as 'dudes built like brick shithouses use supernatural martial arts to fight vampires and similar vampire-like beings'. Part 2 is particularly awesome since it's got cyborg nazis and the greatest protagonist ever.
Afterwards, the focus shifts to abilities called 'stands'. Which are basically kind of a guardian spirit that 'stands' by the character who summons them. Only people with stands can perceive other stands, everyone's stand has a unique ability, and as an archetypical battle manga the series is all about the crazy fights between the protagonists and whatever weird-ass opponent they run into that week. Stand abilities can be conventional like simply being strong and fast or controlling fire, or abstract like 'if you lose against me at a video game, I steal your soul'. Most of the characters in this game are stand users.
