Hi TK,
Let me be the first to welcome you to the forum. You have chosen an excellent car - did you go for the saloon or the Touring model? What about colour? Anyway you should come over and join the rest of the gang at the European & Diesel pages at
European & Diesel Powered 300 Models You can pick up most of the basics from skimming back over previous articles but one thing about this site is that I have never heard of anyone being slagged for asking a question - never mind how often it has been asked before. All that will happen is that someone will post a link for you to go and read the earlier article. You will also find on the European pages a sticky at the top which has copies of an image which you can print out Tax Disc size and place in a tax disc holder and display on your car to show you are one of us. Anything else - just ask - and remember and keep the big grin on the face when driving -the rest of us do!!
Cheers John
