That's right, 2007 3, 5 & 7 series have the option to get the free maintenance upgrade at NO cost.

BMW has announced a limited-time offer, running from February 2 through March 31, to extend the no-cost maintenance coverage on some U.S. Certified Pre-Owned (CPO) cars by an additional two years or 50,000 miles.

With this offer, buyers would be covered by warranty for six years or 100,000 miles from their original in-service date from new, as are all of the company's CPO vehicles, but after BMW's four years or 50,000 miles of full maintenance coverage normally expires, they'll get a complimentary two-year/50,000-mile upgrade, extending hassle-free driving into the years when maintenance might begin costing a little more.

BMW's included maintenance plan fully covers normal wear and tear, such as brake jobs, oil changes, and other maintenance, and even clutch replacement-receipts that could stack up to $1.800 without a plan, says BMW.
