I'm hoping to buy an XJ in the near future, and I'm just having a bit of trouble working out what comes as standard and what the extras are. I'm probably looking at a 2014, as I think there was an upgrade to standard spec on that year. Is there a list anywhere of what is standard? Also, what is the difference between ACC and cruse control with automatic speed limiter? On one guide I've seen, it says you can set the distance of the gap to the car in front with the cruse control with speed limiter? I thought that was just on ACC.
