As it turns out, the C63 AMG with its "M156" 6.2 V8 engine is the cheapest (by nearly £20k in Britain), but the level of craftsmanship in the GT-R's engine is still fantastic. If I had a GT-R and saw this video, I'd check the name plate on my VR38DETT and probably start to think of him as I drove it. Also, I think that's Owen Wilson narrating, in a slightly disinterested way...

Some extra text from Worldcarfans:

The workers, known as takumi, have over 100 years of combined experience which helps them to piece together the 374 different components in approximately six hours. Once the engine is competed and has undergone an inspection, the workers install a named plaque as a "pledge of quality."
