M aero kit is the top of my list. The dealer's package is vey tempting, can even do interest free installments. But my wife won't approve.
May be later, and may do it outside so it's cheaper. You made me jealous, bro.
I think the M kit is the coolest, but if I do it I will do quad exhaust together, but it's damn expansive. Talking about the hamann or supersprint which are the only ones for the 523/528 now. Wonder if any shop can do custom made, should be cheaper. The Southern Cal. guys had it.
Also personally I found the M kit has to go with the shadow line window trims. I have the chrome now. Will break my bank again to retrofit. Wonder if any shop here can do vinyl wrap. I know I can buy the vinyl and DYI, but I don't think I have the patient and the skill.
