DarkRP - Can someone code me some of this?

Hello. I got a DarkRP server hosted at Bioservers.

But… I got some stuff that i really want to have.

Instead of the Veichles in the Q-Menu - Then I want people to press F4 and then go to Car Dealer. Buy a car for 500$ and then it spawns in front of them, with the person as owner. The purchase then have to be saved. So the next time the person wants to buy a car he just click on it, and then spawns it for free.
Also when a person owns a car, then if he leaves it, it have to be auto locked.

Car damage. If a person shoot on a car, it will go on fire if damaged enough. And eventually blow up and hurt person inside for 80damage and people around for 50.

I don’t mind paying a small amount of money for the above.

Also i got these bugs on my server, can anybody tell me how to fix it?

Thank you.

You might want to post this in the lua scripting request forum, http://www.facepunch.com/forumdisplay.php?f=53

This is already in Darkrp here
in AddEntites(darkrp SVN) or addShipments(olddarkrp)
do this
[lua]
AddCustomVehicle(“Car”,“MODELHERE”, 10000, {TEAM_CARDEALER})
[/lua]
and in shared.lua do this
[lua]
TEAM_CARDEALER = AddExtraTeam(“Car Dealer”, Color(51, 51, 153, 255),
“models/player/gman_high.mdl”, [[Sell Cars to people.]], {}, “cardealer”, 10, 50, 0, false, false)
[/lua]

WarJunky . I’ll just make a thread over there then.
And Ghost… I don’t want a guy who sells cars. I want everybody to be able to buy a car. And saving it too.
Nevermind.
