Tuner Tuesday: 2008 BMW 550i M-Sport Dinan 5

I still remember well when the new E60 5-series launched. I was not impressed. It looked modern, sure, but it also looked very heavy and it was full of odd angles. It was expensive, too, and though the M5 came with a massive screaming V10, the rest of the run seemed to be pretty tame. But BMW offered steady upgrades throughout production, and the post-LCI sedans really came into their own with the M-Sport package. A few weeks ago I posted a ’08 550i M-Sport 6-speed on our Facebook page, and its popularity proved that more people are beginning to appreciate the performance value offered in this unique package. Having spent the past half year with a E61 Sport, they are really fantastic cars to drive and ooze quality and you can count me among the converted. Today I have another 550i M-Sport 6-speed, but this one has been turned up a few notches by Dinan:

Tuner Tuesday: Dinan-modded 2008 BMW 550i

Perhaps it’s fitting that if you hit the shift key on the keyboard when attempting the M-Stripes in script you get three questions marks. We’ve recently had a few features questioning whether or not you need the ///M Badge on your 5-series; most recently, Paul looked at the E34 lineup with his M5 v. 540i post. The question has remained throughout the various iterations of the 5-series; while there was a pretty big gap in performance between the E28 535is and M5, those gaps have narrowed in subsequent generations. Couple that with the increased costs of ownership of the M-branded 5 and the higher residual value, and there are some good arguments to look at the top-of-the-range normal 5 versus the Motorsports version. When it comes to the E60, that’s especially true in my mind; the M5 had that great screaming V10 motor and many are fitted with the 7-speed break-your-neck-shifting SMG gearbox. Those are great items to have when you don’t have to pay the bills to repair them, but now the best part of a decade on despite the inexpensive entry price for E60 M5s relative to the performance you’d get, they just seem like a nightmare to undertake ownership of. The answer, then, may be to find a lightly warmed over 550i:
