I have a disco 300 Thats modded and a standard 2.0 frontera sport and they both go over and though all the same bits on my play site ?
I have both so can comment.
Fontera £500
Disco £3000
Bit of difference really. They were never aimed at the hardcore offroad brigade and driven properly will go most places .
My fontera is about to have a 3" lift, 33" tyres arches and spacers, Oh and a 9500 winch and bumper to pull stuck LR owners out
My disco is for work so has to earn its keep and does so well but they are not cheap to mod or fix .
For your budget I would say 200 Tdi as they are simpler and are cheap enough to buy.
