Apologies in advance but I did have pictures for this but it seems they are too large! Just back from a Euro road trip. Went from Calais to Lake Constance for two days then over to Austria for a week to do Ironman Austria and finally off to Stuttgart for a tour of the factory. As an AMG owner they will give you a free private tour of the factory and facilities including meeting the guy who built your engine. My other half was very skeptical about the whole thing as she has little interest but even she said how intersting it is. You start off with a tour of the showroom and get shown all the models and have all the specs and details explained. This included a GT3 and GT4 racer which were very cool. The ultimate boys toy? You thenget taken into the factory. No pictures allowed which was a shame. They show you the test rig. All new engines do 500hrs on the redline! Saw the new 2 litre being tested. They then show you the one man one engine set up. Theres 2 approaches now. The original where the guy has a trolley and walks the engine down a horseshoe line while he adds bits to it. The new floor for the latest 2.0 is much cooler. The guy is static and robots bring the parts to him as he completes it. All in all really good couple of hrs and well worth it if you get the chance. The staff were so friendly and knowledgeable and didnt even mind me turning up in the 335d!
