E39 is a pinnacle in automotive designs, the last year 540 with M-package is THE bomb!!! it is the next best thing to E39 M5 without actually going overboard and mortgaging your kids!!! BMW of Arlington is nice dealership, my 4.8iS was maintained by them until i took it over... took over the car, not the dealership!!! i don't know anything about the nissans, but it is for sure not a BMW...

go for it!!!
