I never thought the waterproof Pessima would be so popular. People are calling it an amazing mod and want me to make more (one user even wanted me to make all cars waterproof, but I think he went too far). So, here you go.
This pack contains 5 waterproof cars: very powerful drift-tuned 200BX for underwater drifting, H-series with 4wd, offroad wheels and increased engine power and ride height to overcome moderately rough underwater terrain and move through water on considerable speeds, T-series box truck with a large turbo to drive faster underwater and, finally, very powerful D-series with offroad suspension and tires, capable of overcoming even the most extreme underwater environments. Update 2.0 also brought a Bolide.
These are the last waterproof bottom-driving vehicles I make. To people who want more and more waterproof cars like in this mod: come on, if you want it, make it yourself. All you need to do is copy an engine and remove one line of code from jbeam.
