The only model currently available is the 2011, are there any plans to make another boxster spyder in the future
Likely yes, but not for a very long time.
Special edition models like the Spyder don’t come out until the end of the generation to spur last minute sales.
With this new 2013 model, I don’t expect them to design a new generation for another 7 years or so. I expect the next Spyder variant to come out around 2020.
