I've just been offered a 2009 X5 M Sport (35D) in black. 145k miles but lot of work done. Complete new suspension, airbags, pipework, compressor. All injectors he said replaced but need to check that as I am told the only proper ones are £1000 each due to only Bosch being able to replace the important bit (Piezo crystal).
You would do better to ask in the range rover section for tech advice. https://www.landyzone.co.uk/forum/range-rover.10/
After visiting the Introduction section to show us pics and tell us how much you love/hate it. https://www.landyzone.co.uk/forum/introduce-yourself.20/
See you there
will look for the amount required.
