So in the parlance of the Land Rover world - what is my '06 Range Rover HSE?

Is it a Mark III? A Range Rover? An LR3?

Where in the Forums do I find folks with similar joys, problems, issues, mods, etc to my own?

 

a little of both, 06s still had a bmw bcu unit. So if you problems with locks and windows and pdc you hooked up testbook. pcm and tcm were jaguar based but the body systems were bmw based. They ran on a completely different system. Suspension wise its the same parts are the same. Interior parts are a different but similar. you will find the attaching points different. The entertainment system is the same as 05.
