Like the ad suggested, I made my deal on a new C300 at my local MB dealer on Monday. I planned to use my MBCA $500 certificate as down payment but didn't let them know it. We did the paperwork then and scheduled to pick-up the car Tuesday (yesterday). Once we signed the final docs, the sales rep said "all we need is a check from you for $500" and in response I handed over my certificate. He took the doc and handed me the keys and said..."we're all set...enjoy your car!" Even though the program is down from $1000 a few years back, this program alone is worth being a member to me.
