I was mulling over moving up to an R231 SL500 but this new model seems to have stalled the market for the 2013-2015 cars, for example local dealer Tim Purslow has had three R231 Sl500s on sale for several months now. Maybe the demand is either for the 400 or the 63, the 500 in no man's land? Maybe pick one up in the winter for 30 to 40k?
