I meant to add, not only are the models different in feel but cars of the same model can vary. For instances I have driven one Roadster S2 that just did not drive and feel right but the next felt great. So it can be difficult, my conclusion was that it depends on use and care of the car, I found mine got better through use, sitting about IM does not do them a lot of good in the long term. Things go hard a sticky!
