Yeah, Jason, I was just having tough a time telling the difference with the cars in the pics. Thought maybe you knew off the top of your head.
Looking a little closer, it appears to me like this:
AW 328i Sport = 18s
GS 335i Sport = 18s
MR 335i Sport #1 = 18s
MR 335i Sport #2 = 19s
Edit: Upon further examination it appears there are two different GS cars too - one with the 18s and one with the 19s.
Anyone else agree with my list, or am I off?
