C43 AMG, hmmmm?

I'm looking to take my first step into the world of luxury vehicles, tho a cheap, 10+ year old car is a small step indeed. I've been reading a lot about these recently but I'm still lacking personal testimony. Have any of you had these? Definitely have a few questions before I make the purchase.

I'm not 100% decided on the C43 but it seems to be the most bang for my buck as far as older model AMGs are concerned. If you guys have recommendations on other, similarly priced, AMG models I'd welcome that input as well
