I am looking for a new (to me) DD, should be reliable, not too expensive to maintain, and a good drive. I found a 2006 C55 AMG with 76K miles which I am going to look at in the next couple of days. Any suggestions on what to look out for beyond general condition? I believe the M113 is fairly robust but am not really familiar with it. If not this C55, any other thoughts for a DD? Thanks!
