The A-Spec body bits on actual factory-stock A-Spec cars was part of the package that included the few other items mentioned previously that made the cars differ from the regular TLs. I don't think that's ricey, although I don't particularly care for the look. However, putting the A-Spec bodykit on a regular TL
would qualify as ricey in my book. Likewise, an M5 bumper on a regular 540i would be rice; the same bumper as
stock on the 540i M Sport is factory rice but I can let it slide. Basically, if the A-Spec body was the only difference between it and the regular TL, I wouldn't necessarily mind someone adding those bits to said regular TL, though I'd view even the A-Spec as factory rice; however, because there were other differences, adding the A-Spec bodykit to my TL would be ricey and, in my opinion, hardly better than an aftermarket bodykit.
TL;DR - no cosmetic modifications for me.

I stand corrected.

I remembed it was the TL for some reason, but they do look very similar. Do they share any greasy bits?
I don't believe they do but don't take my word for it. Certainly different engines and at least the manual transmissions are different. I'm pretty sure the chassis are different too.
