OP UPDATE: Thank you to everyone that contributed to my original query.
Ordered this week from BMW of San Antonio for Performance Center Delivery. M235i/Mineral Grey Metallic/Coral Red/Premium/Technology/Heated Seats/ZF8/Black Kidney Grilles/Summer Performance tire package/BMW M Performance Exhaust without diffuser.
Kudos to Jim Wester, Sales Manager, (210) 801-8188,
jwester@principleauto.com. Very refreshing to deal with someone like Jim. He knows the brand and earns his customer one person at a time. Best deal I was able to find after scouring Southeastern US (at least a dozen or so dealerships). Most strongly recommend him.
