Greetings! I tried the search but am unable to find the differences between the model years. I'm looking for a convertible in the 2006 to 2009 range. It appears the convertibles went turbo in 2009 and the coupes in 2007? What is up with that? I definitely want an S model and a stick. So, it would be nice to know: Chassis changes throughout the years Engine changes throughout the years Options groups Are any of the years inherently more reliable? I prefer the models that have the speedo and tach above the steering wheel. What option is that called? Thanks to all who reply!
