Here are a couple options for vehicle mods if you're interested in checking them out. I won't give links because then the post won't show until approved, but I'll say where I found them.
From the mods forum here:
Vehicle Madness by Ragsy (already discussed)
AH-64 Apache Helicopter Mod by Zilox - adds that one helicopter
Boating Modlet by Ragsy - adds some boats
From Nexus Mods:
Bdub's Vehicles by bdubyah - adds a lot of vehicles
IDC's The Nomad - Crafting Capable Vehicle - Ultimate Mobile Base by idc12 - add an RV that allows crafting and has a weapon (I think this is the one that teleports you that I mentioned)
DK's Modern Vehicle Pack by dk710 - Adds a variety of vehicles, mostly sports cars
Server Side Vehicles by arramus - Adds mods for vanilla vehicles that can make the vehicles look different
I know I saw another one that had a small selection of vehicles, but I can't seem to find it right now and there are probably some more.
