Was thinking a quad myself but then there the prob of getting it to and from shooting area.
Could drive it but then u need to register it tax it m.o.t it insure it.
And the you have something with litte storage room not as comfortable as jeep colder and of course u will get wet if it rains.
In my opinion only mine so no one take offence the best simplest option keep car and get jeep aswell, get something like a old vitara or jimny for say 800 to1000 insure it 300ish for me. Same price as a half decent quad.
Depends how much ur insurance is to make this worth your while.
