Well we know one thing it is not a bonneville..After oing some research it looks an awful lot like a BMW E46 (3 seires) produced from 1998-2005 due to the high mount brake light and the turn signals on the fenders;Also the BBS style wheels
Note here on this E46 the high mount also how the taillights kind of wrap the sides as you can see in your pictures
And only the more ''expensive luxurious cars'' came with those fender flashers I.e. Lexus BMW and some VW'*..
Then if you look here and again at your photos notice how there is no ambient orange close to the grille from the parking lights.yet in yor photos its on the outside just like an E46.
Just my opinion hope this helps
Also the more common name for this car is a 318i
