Tuner Tuesday Dinan 5-off: 2008 M5 S2 5.8 6-speed v. 2001 540i 6-speed

I know that, amongst the authors that grace these pages, I seem to do a lot of comparisons of cars, some of which are extremely unlikely comparisons. One of our readers termed my picks a “Cheese and Chalk” competition; in many ways, he was right. After all, how can you really compare cars that are in completely different demographic categories? To be fair to me, I don’t always do such, but in that case that’s the appeal of the “10K Friday” series – taking a fixed budget and looking at the wild variety of cars that’s available simply because they’re similarly priced. However, I also like to compare similar vehicles and that’s the case today. I have two rare examples of Dinan-modded BMW 5-series. On the surface, they’re quite similar – both grey metallic, both with light grey interiors, both with normally aspirated motors, both have silver multi-spoke wheels with polished lips, and both have 6-speeds. But the level with which Dinan has breathed on them is quite different; consequently, one has double the power of the other, more technology and more complexity. That model also has one tenth the mileage of the other, and unsurprisingly is on offer at ten times the price making these seemingly very similar 5s very different. Which is the winner in your mind?
