I would just like to add; do your research on AMG's before buying one. I've owned an E55 AMG and I've never seen a car depreciate so bloody fast. I bought it used, must have been about 5-6 years old and I had paid 30k (70-80k loss in 5 years).
I can remember giving the owner the 30K at the bank, him putting the 30k + roughly another 30K from his pocket just to pay it off to legally sell it to me. I was stunned he still owed 60k on the thing. I sold it 5 years later for 18K. 110k to 18k in a little over 10 years.
If you do your own work, they are fun cars but parts are bloody expensive. If you intend to always have it serviced at the dealer; forget about it. I remember going to the dealer once to get an alignment due to the air suspension (most other shops didn't want to touch it) and got quoted 600$ for a 30min job. After a few choice words, I walked out dying of laughter.
