InfoPresenting Mega Mario! A ton of hit points and can smash through anything.
Spawn the mega mushroom from the phonebooth and when you get into the vehicle you will be mega mario!
I've included a forced mega mario setting setting as well, which forces mega mario for every mission. This was with some help from EnAppelsin's forced car lua scripts which you can find here: github.com/EnAppelsin/SHARForcedCar
After creating this I realised there is a more optimised way of doing this but oh well :)
You can decomplie the mod and use it for anything.
