I just traded my '06 750Li lemon for an '07...and got another lemon. The '06 was continually in the shop for transmission problems, which after 4 attempts and a new transmission was never fixable. The new '07 has the same problems (I know, "fool me once..."). BMW as a company has been horrific to deal with. The mechanics say that BMW is well aware of the faulty transmissions, but no fix is available. Apparently BMW's policy is "let the buyer beware". Yikes. I now have an attorney instead of a drivable vehicle. Oh well, live and learn! I guess there is good reason why the A8 and the S-class have passed up the 7 series in reviews over the past several years.
It's in the shop too much to remember.
1)BMW needs to fix the faulty transmission problems. 2) BMW needs to return to the principles of ethical support and business conduct that helped build their reputation.
