I will say this again, if you drive 100% on the street, there are better SUV's out there than the RRS. If you want to do some offroading and drive on the street, then the RRS and RR are in a different league. But since they are needlessly complicated for the street, more stuff tends to go wrong.
In addition, reliability will always be an issue if the British and electronics are involved...its a genetic/cultural thing. Having said that, the Germans have issues with electronics themselves, primarily related to their strange obsession to control everything in the car with one knob. Which unfortunately, seems to have caught on with the rest of the industry.
