OK thanks anyway, just have to keep looking.
So sturose, you are looking for a 7 seater Disco, you seem to be opting for diesel? and it sounds like you haven't done much work on cars before and you want the vehicle for general running around not just off-roading - would that be about it?
Do you have a preference for manual or autoboxes?
If you want cheap and basic transport with a good level of reliability and cheap to fix, I would suggest a Tdi 200 manual. If you want something that feels a bit more refined, go for a Tdi300 either man or auto.
The crucial issues with the 10yr+ Discos is RUST RUST RUST. Most of the common mechanical problems are relatively straightforward and reasonably priced to fix.
Have you found an LR specialist garage close to you yet. Getting servicing done at LR dealers for older Discos is an expensive nightmare, so plan to find a local specialist.
Have you driven any Disco's yet. Not as daft a question as it might sound, people often buy Discos without driving them for a number of reasons and then complain that they don't run/drive properly. These vehicles weigh over 2000kgs and only have about 111-120bhp - so they are slow & large by comparison to driving an average family car - are you ready for that?
Please don't get me wrong, I love my Discos, but I do all the servicing & repairs on them myself so the costs are very low (parts are cheap!!) and I have realistic performance expectations.
MPG for example, are you ready for 30mpg for a diesel, 14mpg for a V8 petrol?
Do you see what I'm getting at now? I wasn't trying to be argumentative, I was just trying to get you to tell us, what your needs/wants are, so that we can advice you constructively.
Good luck
Dave
