My guess is you are looking at a BMW engined 2002>2005 in which case all financial advice aside ( and it's sound advice) off the top of my head for the milage you will be looking at check;
PSV hoses have been replaced , if not be aware
Plastic timing chain guides have been replaced , if not be aware
water cooled alternator has been replaced , if not be aware
Sealed for life gear box has had regular oil changes , if not be aware
Diff oils and transfer box oil has been changed , if not be aware
Rear electrical units under leaking tailgate have been kept dry , if not be aware
Suspension compressor revised or changed , if not be aware
Suspension airbags have been changed , if not be aware
Front prop shaft was replaced by Land Rover , if not ,,,, you know what by now it's probably fine.

Of course this is a online forum and you will only hear horror stories so to put things in perspective over the last nine years I have had two Range Rover L322's and in that time apart from wear and tear items I have replaced one suspension compressor ( and that is a wear and tear item really ) an O2 sensor and two rear shocks . That's it nothing else and I have towed heavy trailers regularly and drive off road a bit as well . But here is the BUT , never scrimp in servicing , fix something immediately and use genuine parts, it's not cheap and as they get older it doesn't get much cheaper .
