I can't help but love the lines of the JB 700, and fully upgraded it isn't a slouch. It might not handle like the monroe, going off other posts (I have no experience with that car myself). It isn't terribly common online, and is a great choice for standing out. With the right color schemes, you can kind of mitigate the unpleasantness of the tacked on shotguns. I still wish the decommissioned version had those removed entirely. She's served me faithfully against plenty of assailants in free roam, both in fighting back and putting asphalt between me and them.
She also looks downright gorgeous in white walls.
Edit: Just realized you already decided xD My two cents on the matter still, at least
