I can't sleep....I'm so nervous.<br> <br> I'm getting a 2001 E55 (black) delivered to me and it will be here tomorrow afternoon. I am very nervous, since it was an online/telephone transaction, and I have not seen the car in person (I had a MB dealer do an inspection, plus I received 15 pictures of it). I'm a nervous wreck. I did have the chance to test drive on at my local dealership, and I was impressed with the power, acceleration, blah, blah, blah (I'm sure you guys can fill in the blanks).<br> <br> I know the E55 is a relatively new car/series, but are there any problems I should be aware of? The car has 15k miles, so it's still 'new'. But I've been around German cars all my life, and I know most of them has their tiny querks or possible problems (BMW 850 and electrical problems, 80s Porsche 911s and their head studs/valve guides/leaking problems, etc). Anything I should check/test first on the E55? Any known issues? I realize this is an open-ended question, and I do apologize for my lack of detail.<br> <br> In addition, the car needs new tires. I'm thinking of Michelin Pilot Sports or the Pirelli Pzero Assym Rosso or the Potenza S0-3. My co-worker suggested the Kumho ECSTA Supra 712, which costs 1/2 the price. Any suggestions?
