He tells customers that they are almost impossible to re-sell. If that's true, I certainly don't know why.
OK, that situation makes sense. If I wanted the SLK for just a cruiser or GT, it would make sense to go with the auto. And frankly, the SLK would make a great boulevard cruiser or GT.Your father is correct, IMO, and I AM an old fart. It may sound strange, but I wanted the 7 speed auto on our SLK 280 -- but only because I wanted it for a GT car, and we already had a "pure sports car" complete with 6 speed manual. But not everybody wants an SLK for the same purpose and use, so I don't understand why 6 speeds allegedly don't sell.
