Well done on a good choice of vehicle
It would do you good to look back over this forum from November to date, as pretty much all of the popular issues were covered....
Popular issues are ... parking sensors, rear air suspension, air pumps & other little sensory or electrical gremlins that may "seem" horrific, but actually most a pocket-money fixes.
These vehicles are absolutely solid,..... but do need care and a little TLC.
Some mechanical/eleccy issues may seem nightmareish to a newbie, but most are actually VERY simple...
and knowledge saves countless £££'s.
You will find the guys n girls here very helpful, and a fountain of knowledge when often the Main Agents will rob you bare or be clueless.
I've owned all sorts before, but gotta say that the friendship and help here is amazing.
Enjoy & be safe.
