So, as I seem to have asked most questions, I may as well continue.

What is seen as the best set of vehicles in Dayz?

Land - I have an SUV Special but I'm finding it rather large to manoeuvre.

Chopper - Just picked up a U1H1 or whatever they are called

Boat - Havent seen one yet but will go and get one later on.

Cheers

i think you can t say this is the best car, boat etc..If you are alone, you probably dont need a heli with guns. There are cars for different situations. for looting much place; for missions good guns, etc.. I personally use everything i can get. mostlikely a fast heli like the mi17

Fastest vehicle on road: SUV Special
Faster vehicle off road: BEAST aka Kamaz transport
Fastest boat: Submarine/CRRC
Fastest heli: HC3 Merlin

Personal favorites
Vehicle: SUV,fast and silent car with space for 6 people. Also fast off road.
Heli: Blackhawk, 2 m240s on each side and good maneuverability,OR Mi-171Sh.
Boat: RHIB, 50.cal and room for +6 players, a bit slower than CRRC.
