This mod adds a car (an old one), the 313 (Donald Duck's car), a Jeep, a Ferfari (joke with Ferrari), a Blue Car, a Yellow Car, an Old Car and a Van.
You can enter and drive every car, and every car has its own speed.
There are also achievements on their own page.
This mod also has it's own creative tab.
