@NateMachpash

It refers to a car that has been on the market a while and undergone changes to the interior, exterior or engine system.

For example, in 1999 the Honda Insight (a hybrid electric vehicle) was a 2-door liftback; in 2009 they made some changes to it and it was a 5-door liftback: in 2019 it became a four person sedan. There were also changes made to the engine, etc.

The 1999 is the first generation.
The 2009 is the second generation.
The 2019 is the third generation.

I hope this makes sense to you!
