[NEED HELP URGENT]Cars Mod -- please help

ok well heres the recipe for first release

it is simple enough for people to make cars and be happy with the release and as for the block id id say block number will be 171 for the car since the block number doesnt conflict with any other mods and block numbers. some people may be spawning cars with too many items more often but for this release car i dont really want it that way cause i want people to be able to make simply and not have to cheat XD. Compatibility i would like for it to be modloader compatible cause then it would work with alot of other mods and i know people would love to have this working with other things. It wont need sound till we add a couple more cars and when that happens well have to make it audiomod compatible but for the first couple updates and release no sound from car. other stuff in future will require minor tweaking but other that that we good.
