I like them
Avoid the 51-02 plates, ideally buy 03 onwards
You'll much much much prefer the 4.4, tbh the td6 is horrible in a Range Rover but it does the job admirably and they're still a lovely car
Definitely spend more to buy one in good cosmetic condition, otherwise you won't get the full range rover experience
The interior needs to be clean, not worn and not smelly, and you could be In a much newer car as far as you'll know
06 facelift models look newer but a nicely modified preface lift looks very good in its own right, I have only met one man however who in my opinion knows how to correctly modify an l322 to improve its appearance and believe me plenty have tried and failed
The v8 has a number of high running temperature related issues, all cooling system components will fail eventually due to extreme temperature, breather hoses too, alternators can go
Spend decent money having the autobox stripped and sorted out by a proper l322 enthusiast specialist as soon as you get the car or don't expect it will last forever
They often leak in the rear which buggers the sat nab drive but they can be replaced
All in all one of my all time favourite cars, v8 is THE Range Rover, td6 is trying very hard to pretend
Cheers
