Buy a 2003- 2006 used Mercedes, NOT C-class (because C stands for cheap). Maybe a CLK or E-class. People are so blinded by the Mercedes sign most people won't know it's used, especially if you buy a recent model.
Even better if the Mercedes sign is big and in the grill so everyone can see you in their rearview mirror
Certified pre-owned looks just as good as new and is not likely to have too many problems.
