Great location to check your carbon footprint and do the global warming / global cooling dance. It is mandated that you get your vehicle tested once they turn 5 years old or older so you can then shell out some serious ducats for a new shiny sticker.
I have been to several locations throughout the valley with company vehicles as well as my own and this one so far is the best. My older Mercedes turbo diesels were like a couple of mosquito foggers and no longer could bare this "do si do" and they were happy to let me know. Sadly I miss my 300TD and 300TDT built in Stuttgart with over 2 tons of bulldozing madness. Auf Wiedersehen!
I arrived at 4pm and was out the door in 10 minutes. Maybe I just got lucky this time but they say luck is when preparation meets opportunity. Good luck and hope your ride passes with flying colors.
