Spotted 2 M3's at the Willowbend Mall in Plano.
The first was a SSII e90 M3 w/19's.
The second was a black e92 M3 w/19's.
Btw, I thought it would be worth mentioning that I also spotted a silver Carrera GT while I was on my way home.
And some kind of expensive Bentley coupe was in front of it, so I guess they were both together.
