unfortunately, yes. just a opinion of mine. i'm sure the OP will make a good decision and put a spoiler on his car that looks good and that he likes. which is really all that matters. he seems to have a good grasp of what he wants, so i hope he finds something that fits his style and taste.
i'm assuming here that if i could afford that car i could afford to take the spoiler off.
of course if i were racing my car on a track and the spoiler was functional, then that's a different story. but, for every day driving i'm not a fan.
I'd do a CSL trunk before a spoiler.
