Some road trips are about scenery. This one is about horsepower. A German supercar tour recently strung together three of the country's best-known performance shops, Brabus, Manhart Performance and Pace Cars, into a single run through the parts of Germany where the tuned cars actually live.

MSN covered the run, and the photos alone are worth the click. These aren't the builds you see lined up outside a valet stand. They're the rare stuff, one-off and limited-run cars that spend most of their lives in workshops and only come out for exactly this kind of thing.

Brabus needs no introduction if you've ever scrolled past a blacked-out G-Wagon doing something unreasonable. The Bottrop outfit makes its name pushing Mercedes vehicles well past what the factory considers sensible, and from everything I've seen and read the place feels less like a shop and more like a monument to going fast in expensive clothing, though I haven't stood in it myself. Manhart, over in Wuppertal, works similar magic on BMWs mostly, with a side of Audi and Mercedes when the mood strikes. Their builds tend to be the sleeper type, cars that look almost stock and then absolutely are not. Pace Cars rounds out the trio as a specialist dealer and preparer, the kind of place where the inventory rearranges your whole afternoon.

But Germany does car culture differently than we do. Over here, a performance shop tour means driving to three strip malls and maybe a warehouse district. Over there, these facilities sit in real towns with real driving roads between them, and nobody covering that ground in something seriously tuned is in a hurry to get it over with.

What I like about a trip like this is that it treats the shops as destinations, which they are. We plan whole itineraries around diners and roadside attractions, and I've written plenty of those pieces myself, so why not around the places where rare machinery gets built? Same instinct. You want to see the thing made where it's made, talk to the people with grease under their nails, and stand next to a car that maybe two dozen people on the planet will ever own.

I've done the factory-tour version of this a couple times, museums and tuning shops on various European trips, and the gap between seeing a build online and standing in the room with it is enormous. Photos flatten these cars. In person you notice the wheel fitment, the seam work, the way the exhaust note bounces off the shop walls. It's the difference between a trail map and the trail.

If you're planning any Germany driving trip, I'd look into folding a shop visit or two into the route. Can't promise any of these places take walk-ins or tours, so check before you build your day around it. But the driving between Bottrop and Wuppertal alone strikes me as worth the mileage. And if a Manhart-tuned M car doesn't interest you, we need to talk.
