The car that Bulma
drives in DB001
is teal with 'TURBO' written on the side, and featuring a number plate reading 'PFF8801'.
Bulma's Car is destroyed by Son Goku while she's travelling through the Eastern Mountains, as he believed it to be some kind of monster.
It's a Hoi-Poi Capsule car, and is quickly replaced by Bulma's Scooter.
