Dude it's not rocket science. There are a few ways for people to make cars. They can either use AddStaticVehicle, AddStaticVehicleEx and CreateVehicle. Press CTRL + F to load up the search box, and find all of these and delete the lines. The lines would look something like this:

CreateVehicle(401,342.848,159.493,583.148,45.3,,0, 0,1200);
AddStaticVehicleEx(401,348.573,582.485,284.472,54. 1,0,0,1200);
AddStaticVehicle(401,3481.583,2959.471,582.5821,31 .4,0,0);

The numbers will all be different, but the first words and then open bracket will be the same. Search for them and then simply delete them.
