We're brothers from another mother mad4che. I have a 325i daily driver and been waiting for an E90 M3 sedan to be a do it all family and track car. But car guys get inpatient leading to buying a CS as a stopgap car until the M3 arrives and I sell both the 325 and CS.
Unfortunately, I'm having such a great time tracking the CS I don't think I can sell it, hopefully I'll get to keep both and sell the 325i, that would be the dream team. I'm waiting for a M-DKG car to be delivered in July. Good luck, can't go wrong anyway you slice it.
