Conventional wisdom says that the price of convertibles goes down this time of year. I have been wathching CLK and SLK prices on Autotrader for around six months now, and they do not seem to be any less than they were in the summer. In fact, there are some seriously over-priced CLK convertibles out there at the moment, and the prices do not seem to be coming down. Is there really much seasonal variation in convertible prices, or is it a bit of a myth?
