WOW. Thats a bit harsh.
I personally own the X6 and the X5. My problem with my xx4 was it was fast but wanted to "tip" over on high grip corners. and grip roll slowed my times down.
I converted my xx4 into the x5^2 and it was just fantastic (in my opinion
)
The problem i had with the xx4 had gone and the car was just consistant. the only thing i have broken is the front shock tower But lets be honest on the xx4 its the same problem, the graphite towers are rubbish. Since i have put braces on the front and rear shock towers and converted to the X5 i havent had any problems.
sorry dude in my opinion car is ace.
