Tuner Tuesday: 2006 BMW M3 Dinan S3-R

My ongoing search for a clean E46 M3 continues, and despite the relatively high number produced it does indeed seem more difficult to track one down than it probably should. Early cars are typically more suspect, with many owners, dubious modifications and higher miles. Additionally, my criteria for getting into an M3 is admittedly limiting. The car must be a manual gearbox, and given that I have a preference for some of the more expressive colors like Laguna Seca Blue and Phoenix Yellow, that seems to be more difficult. But in my search I happened upon an unexpected gem that threatened to turn my head from the Crayola-toned early examples; for the most part, I’ve ruled out the later M3s because they demand higher asking prices and there seem to be less in wild colors. This car stood out for not only being the last model year of the E46 M3, but also because it was a ZCP car. Though I’ve sworn I’d never voluntarily buy into another black car, the ultra dark midnight blue hue of Carbon Black Metallic is compelling enough to consider. Add low miles, careful ownership and some discrete modifications from the best in the business to the recipe and this appears to be one of the nicer E46 M3s on the market.

2002 Dinan S3-R BMW M3

Tuner cars can be the stuff of dreams when they’re done right, and the subject of nightmares when gone wrong. Many tuners bolt of ton of parts onto a car, slap some stickers on it, and to be damned with what happens in 10,000 miles – they’ll be onto the next photo shoot. Some select tuners, though, are so good at their craft that the German factories recognize their work as up to their standards. Most of these tuners reside in Germany, but a few have popped up in the United States. Dinan is one such company, good enough at their craft to be recognized by the factory and have the modifications available directly from the dealerships. To be that good requires massive trial and development which comes at a serious cost – fully spec out a Dinan S3-R, and you more than doubled the original list price. The results were as impressive as the list price – 460 horsepower pumping out of the 3.2 M3 inline-6 put the M3 into 911 Turbo speed territory. Today you can pick up one of these rare rockets for about a third of the original asking price – such as today’s Topaz Blue 2002 model:

Model: S3-R M3
Engine: 3.2 liter supercharged inline-6
