Tony, I think me and you have pretty much the same mind set about this car. I was looking into the V6, because the V8 might drink too much gas to the point where it might not even be worth taking for a drive everywhere. Speaking of the electrical maybe the car had battery problems or a shortage somewhere in the engineering. Either way if you dont mind me asking, not to get too personal but how much were you on the monthly lease and how much down did you put. Another thing I love about the car is the beefy rear and front tires, look sick!
Fuel, yes it used a lot. Most V8s do so I knew what I was in for.
Electrical, I took it in 5 times and they could not fix it or explain.
Cost, cars in Australia are about double the cost in USA, with taxes, duties and other govt add ons. I leased it over 4 years witha 30% residual. I won't post exact payments here but will say it was $AU135,000 as a demo with 2500kms on clock.
I also loved the look of it, shape, rear, tires etc. I don't like X5s they are very common here and I wanted something a little different.
