I'm just back from a European vacation and took the time to go to Stuttgart to do the Porsche and Mercedes museums. I recommend both highly to anyone interested in either of the two marques or cars in general. Both are easy to get to on the S-Bahn [train/subway], cheap to enter, and extremely well laid out. The audio guides are well worth a few euros and make the experience much more rewarding. A tip if you go in winter: use the free cloakroom service because you will be inside for a couple of hours at least and they keep the place at about 24 dgrees C, so walking around in or carrying your coat is a PITA.
It is also worth getting a 3 day "Stuttpass" for 22 euros because as well as giving you total access to all public transport in the city and surrounds, including S-Bahn to and from the airport, it gives a 50% discount on many of the local tourist attractions, including the two museums!
Both museums are "attached" to the main dealer showroom so after a look through the history you can browse the current offering at your leisure. A particular feature at the Mercedes dealer/showroom is a section of what they call their "Young Timer" classics. These are cars from the 80's and 90's that have been back throught the factory and restored to almost as new condition and are being sold at [mostly] quite realistic prices. Cars like the R129 and R107 SL's, W123 CE's and W116 cars, all like new with full warranties; magic!!
The blue Cab is a US model I think because it has the ugly black rubbers on the rear bumper, and I was told by a guide at the museum that it was the last 968 off the production line. He also said that in Germany they are very well regarded because they were virtually hand built towards the end. He said that because the factory out put was so slow at the time that the management wanted to keep the production workers busy, so slowed the line right down . Any comments on that??
I took some pics, of the Cab but haven't got them out of the camera yet, but I was asked not to take a pic of the chassis number/VIN...hmmm??
