I would go for the LR3.
For your original budget, ( not sure if sticking a ring on a finger has dented that or not. Congrads regardless ) you can get a nice LR3, V8 with HSE trim and HD package. Will have plenty of cash left over to go round the car, fixing any wear and tear items it will have, like any used car has, regardless of make or model. This will get you a superb base to start your modifiying needs and desires.
The basic car is very capable for off roading plus it has the ability to munch miles like an executive saloon. It's pretty quiet, comfortable riding on the road, has a great sound system and you can arrive anywhere not feeling like you have endured a long drive. Plus it has huge space in it. The boxy nature of the car gives a large boot, the 2nd row seats can fold flat to create a huge open space.
Plenty of companies can cater for underbody protection, sliders, rear wheel carriers, roof racks, snorkels, height rods, tyres, wheels etc.
One of the best things is you can alter, or sort most electrical huffs with an iid tool that can connect to your ipad.
Nwoods on the Lucky8 LR3 thread has a superb off road guide to getting the most from it.
I have written a pretty comprehensive buyers guide for what to check.
The LR3 platform is 10 years old now, all the quirks are well documented online, with guides to fix and rough costs. It's very easy to work on and most mechanical parts have good access.
I have no regrets about buying mine 2 years ago. It's been a great car and has never failed to get me home, regardless of weather conditions.
If your lucky enough to find an HSE with HD option.
