Like Alpina, Dinan has distinguished itself as a premier BMW tuner good enough to get the nod from the factory. But unlike Alpina, whose cars often sport unique trim details, body kits, wheels, and interiors, Dinan’s creations are usually much more sedate – following the Roosevelt-esque ‘speak softly and carry a big stick’ ideology. Outside there’s generally little to identify that Dinan has breathed upon a given model, but depending on what level of modification you choose, they can range from a suspension kit all the way through supercharged monsters with increased displacement. Today’s example, a lovely end-of-the-run E36 convertible, is claimed to have a Dinan S1 serial number, and it wears the company’s exhaust, intake, computer programing, suspension, and a few other details. That alone would probably make it work taking a look at, but it doesn’t hurt that this example is also Techno Violet, low mileage, and has a hardtop. What’s not to like?
