Some advice needed

[hambone1983]

Lately my X5 (83K miles) has been seeing the shop more often than any of my other vehicles in the past! Few weeks back BMW of Sudbury in MA replaced all the seals, gaskets as they suspected oil in the intake. And that revived the X back to life perfectly. Then they noted that the coolant expansion tank had a slight crack while they worked on the motor so they replaced that. And then the hoses to the tank went... Later that week the oil level sensor went out so that was replaced under CPO. Now early this week I noted burning oil smell and oil all under the under carriage... even blew some smoke while driving through the wheel wells.... So back I go to the shop and find out that the left engine head covers might have slight leak of oil from the seals so thats another few days of research and work for them. CPO expired last week but they honored to fix this as a continuing of the same job.... Now I am getting a bit aggravated. Love the X5 but hate driving a loaner all the time.

I been debating if in a few weeks I should trade it in... Want some opinions between a 2006 Cayenne S, 2006 Range Rover Sport HSE or an 2007 E70.

I found a nice EE Sport HSE, 2006 with 70K for $25K - fully loaded beauty but have heard horror stories for repairs?? Enlighten me with knowledge folks.. thanks!
