Where in the UK are you? I'm from Dorset/Cornwall.
I think it's awesome that you are approaching people that use their jeeps more aggressively for their ideas.
However I think most of the people in this particular subforum are the polar opposite of your intended cliental.
I think a fair majority of the people here are bare bones types of vehicle owners with respect to their Jeeps. Probably why they are working on minimum 27 year old vehicles.
Many of us have no heat in our vehicles, most of us have no A/C. My seats don't match anything else, or each other. Hammers are our preferred tool most of the time. We start worrying when our jeeps stop leaking. When there is a piece of metal in the road, we stop to see if it fell off our jeep or we can use it for our jeep.
That said a lot of the members here have beautiful vehicles that definitely turn heads and are very capable off road.
With that in mind, if you want to create a bare bones but subtly refined off road vehicle, you have come to the right place as there is a wealth of knowledge here interspersed with strong opinions and egos bigger than their lift
We generally don't know what works but through many crushed knuckles, we are sure of what doesn't.
Often we are grumpy, crass and rude but its only because we're bleeding from our latest wrenching mishap.
