回複:mfr Tint is the best as it is build in one.
Hopefully it is on the queue. It is already a month. Will call dealer first thing in the monday morning.
I have done some research on 528i and 535, it looks like only difference is on engine (535 is turbo engines???) with $5000 difference on price. I am not a young person (|人到中年|, sad) so that I pick 528.
