The ChiCom car actually looks, from the rear, more like the Lexus I was behind a little while ago (although the tail lights are different). Did you even look at the pictures showing the rear bumpers before you said they looked alike? Hint: the BMW is the one without the indention for the license plate and the cow catcher underneath. And the taillights are not similar at all (and BMW did a much better job on that design element.)
Come on. If you saw the two cars parked side by side in a lot, would you think it was the same model?
Hell...I think BMW has a stronger case to go after Toyota...for stealing the rear trunk and rear end style.
Of course we all thought the early 7 Series was fugly....then the 5 Series adopted it. Now both the Camray and the Hyundai have 'borrowed' it.
