Never did a thread for this on PH, although I did mention it in a few topics. I thought it might be nice to add some content to the new forum, so here goes. I'll do one for my Lincoln as well in a minute.
This is my supercharged L322, which I bought for around 1k, having knocked the owner down from around 5k. Why was it so cheap? Well, the air suspension had collapsed, the engine was knocking, it had various warning lights on the dash, and felt like it had about 80bhp instead of the 400 it's supposed to have. This is how it looked when I picked it up:

I suspected the knocking sound wasn't actually the engine itself, but the supercharger, so we took it apart to get it looked at.


One supercharger rebuild later, and the knocking stopped. I also changed the coils and plugs which restored the power: it now pulls just as well as the other SC Range Rovers I've had before.
Then, it was time to sort out the suspension. Everyone tells you how important it is to keep the air suspension, but with the state of the roads where I live and the extreme temperatures, you just end up chasing constant leaks, so I opted for an Arnott coil conversion. I'm really happy with it - it rides nicely and is more than high enough to clear any obstacles I'm likely to encounter.
When I bought it, it had four different tyres, which probably wasn't doing the differential much good. I decided to change them, and encountered an issue which seems very common on JLR vehicles: the wheel nut covers round off easily and often spin without actually turning the wheel underneath. This particular locking one wouldn't budge at all, and it took two separate shop a total of around 8 hours to remove it.

Finally though, we got it sorted, and I put the new, slightly higher profile tyres on which have absolutely transformed the ride.
Since then, I've just been using it for general work on my land and a few road trips and it hasn't put a foot wrong. It still has a few minor issues (could do with a new key, rear light is cracked, etc) but I considering I'm only about 2.5-3k into it including the purchase price, I think I've done pretty well. MPG-wise it's pretty bad as you'd expect, but that's partly my lead footedness.
Here's a few pictures to finish off with.




Nice. How much is petrol in Mexico?
