If I change BMW 745 Li with my S500?

The new S-class is good, the only competitive is Audi A8 and the Lexus. BMW 7 is out of the range due to it's complicated i-drive and the odd looking. I think they will all have problems, if you dpnt want that to happen i really suggest you to buy the Lexus, everybody knows Lexus's refinement is the best in the whole car industry. I totally agree with the comment above. That's why i suggest you not to buy BMW 7( electronic problems).

All European vehicle is good as the engineering of the car, but not the eletronic part. No matter every where in the world, they are so easy to break. I never lucky to own 7 series or S-class, but according to car and driver magazine. The i-drive(on the bimmer) system is worse than COMAND(on the S-class). It is too complicated to use some basic function.

As my opinion, I will prefer the new s550 because the design, and the interior is much better than this generation 7 series. Also, Benz claims that they have put more money on quality control after the release of CLS model, and I wish they work.

(actually I love A8, but my friend's a4 need to go to the dealership every 2 months for some stupid problem)

Garage ppl told me before that european car has much electronic problems then japanese car is because of the weather in HK......as u know hk is hot and high humidity...........to avoid problem is to check your car more frequently....

I think you more like european car rather than japanese car.......otherwise new Lexus is one of good choice for u....
