Because that's kind of what this guy thinks — and he's driven virtually all the new latest stuff from M-B and AMG. You can check out his full piece on the HP.

 

I'd love to have this car, the upkeep just scares the crap out of me.

 

I own a silver Black Series and it hasnt been expensive at all to maintain. I drive it almost every weekend and sometimes during the week. I spend less than 1000.00 / year in maintenence but most of what I do is based on age not mileage.
I put new tires on it last year and that set me back 1500.00 but that was my choice , not a requirement.
I would buy again if I had space in the garage for another car, and the only car I would consider replacing it with is a GT3RS.

If you can get the car with reasonable mileage and for less than 70k, I would say it is a good buy..but I wouldnt sell mine for that amount. It is an great car and you dont see one everyday, which makes it even better.
