From the day we opened our doors 48 years ago, Otto's BMW has been recognized as THE area dealership dedicated to those who most understand and appreciate these remarkable automobiles. In the beginning, many in this group lavished uncounted hours on their vehicles, tinkering with the engines, adding assorted after-market parts, and making any other upgrades to enhance their personal experience of ownership.

Over the years, an ever-increasing level of design sophistication made it more difficult for performance purists to work on their own automobiles. In 1978, sensing an entrepreneurial opening, Steve Dinan created DINAN CARS, which quickly established itself as America's premiere BMW "tuner." Today, whether partnering with BMW Motorsport to win racing championships worldwide or simply transforming individual vehicles to be the best they can be, Dinan is the gold standard in BMW performance enhancements.

And so it is with smiles and modest fanfare that we announce that Otto's BMW has been chosen to join a select group of dealers nationwide to offer a full range of in-house Dinan parts and services. Beyond their legendary proprietary computer programs, there are also bolt-on options like air intakes, exhausts, and suspensions to enhance performance. We also have wheels and other accessories to complete the distinctive "Dinan look" of your BMW.
