Parking sensors are pretty much a must have item, as the rear window is so high, the bonnet of the vehicle behind just disappears. PDC could be retrofitted if needed.
The Freelander 2 was considered a prestige vehicle, however how prestige it is depends on the model designation, which is directly related to the costs of it. A basic model was just under £25k, a top model was almost £40k. There's a huge amount of toys between the lowest and highest spec, hence the large price difference.
Rear camera is pretty easy to install, once the cable has been run, which on modern cars isn't a difficult task. The camera screen could go in that cubby, where mine has the nav screen.
The audio system is probably the lowline system, but a quick check in the boot for a subwoofer would prove that. No sub is lowline, sub in the boot is midline. The CD player will play MP3 encoded CDs, so there's less need for USB audio. I've added a BT receiver so the girls can listen to music from their phones through the car audio system.
There are several specs of HVAC systems, starting with single zone manual control, right through to duel zone climate control with air quality monitoring.
There 3 grades of dashboard, and several different types of steering wheels, depending on what options are fitted.
It has TR which is definitely worth having, as it not only changes how the AWD works, but also alters the engine response and traction control, depending on the mode its in. Sand mode is great fun on sand, as it gives maximum throttle response, and maximum traction, but obviously it's only supposed to be used on sand.
When the special modes aren't needed, TR is simply left in the off setting.
