Is the quarterpanel replaceable?
If I'm not mistaken I think we just replace the skin on the rear. for the front its a whole new one. The front bumper tends to be what kills you, especially if you run the 2012 version.
I agree in terms of parts the Sm5 is a more expensive car to run then the Miata right now and it will probably stay that way. I think what will dictate the growth pattern of both classes will be what current 1990-97 owners do when they decide to move into a different car, of course SM may continue in its current form for 10 or even 20 more years. It really all depends on the what the owners of the older cars want to do. I cant believe I just put the future of Spec Miata in the hands of 1.8 and 1.6 drivers . What I think is most likely to happen is the proposal you all put forward with regard to the 99-05 is likely to happen, whether its in 5 10 or 20 years is unknown. What is also uncertain is whether or not the drivers of the defunct cars will buy 99-05s or Sm5s. Which way that goes is what will decide the fate of SM in the long run.
