I'm currently looking at 2012/2013 L320 Sport Autobiography's to run along side my 5.0 L322.

I don't want to spend a lot on one as it'll likely snap it's crankshaft at some point so I'm looking for one that needs some fettling. 2002 4.6 Vogue SE - Alveston Red with Lightstone Leather
2012 Range Rover 5.0 SC Autobiography in Indus Silver with Jet/Ivory Interior
2012 Range Rover 4.4 TDV8 Autobiography in Baltic Blue with Sand Interior

Just following up on this and specifically the speedo issue. The speedo/odometer unit has clearly either been changed, or zeroed and I'll have an answer soon on why. The question I need to know an answer for then, is can it be put back to the correct mileage for the car ? I understand the vehicle mileage is stored in a number of areas on JLR vehicles and identifying it with the GAP IID or similar should show the correct mileage.

I'm not too worried about a huge jump in mileage between MoTs as it's easily explained that the mileage has been but back to the correct one for the car. It's not illegal to zero an odometer, but it is to wind it back a few 000 miles. I thinking something like a transfer case module or similar may have been swapped out for a used unit, as I know from my RRS days that these are car specific and this could have potentially affected the mileage.
