I must admit that I have been lurking on this forum for a long time. I have been gathering wisdom before my test drive today. Well, I drove the performance model and it pasted a permanent smile on my face. The 0-60 made me giggle. No car has ever made me giggle. Now, that said, I normally drive like your grandmother. The car that I drove had the larger tires and better brakes. For the kind of driving that I do, I just don’t think that I need that. Has anyone had experience driving the performance with the smaller tires? Does the upgrade make a big difference for someone like me who will never take it on a track? I still have time to change the configuration if need be, but I would love to save the $5K if possible.
