I must admit that I first bought it to flip it. But since gas prices have dropped and are no longer fetching a $2000 premium, I now use it for promotional purposes. I have 1600 miles in 6 weeks and rarely open the sunshade - only to see some street lights. I don't have any problems, but I plan to drive it modestly and take this forum's advice on preventative maintenance. Today I bought a oil filter and 5W-30 Synth oil.
I have had several German cars and the worst was a Beautiful 2007 X5 4.8i Sport. It cost me $75k and had 4 recalls in 9 months, I sold it. If that was the BEST the German's had to offer, I don't plan on keeping this one for long.
In fact I am planning on selling it before the 2yr/24k warranty runs out and buy another one for 2010. Maybe by then they will offer a 5yr/60k warranty without asking a $1500 premium at the dealer.
