I had an early build '12 last and now I have a very late build '14. The 14 is a better car in every way. Quieter, rides better, more stable at speed and the automatic I have now is a blast in a different way than the MT82 was. If you can swing it, the incremental improvements in the car are worth it to get. No way I'd buy an 11 unless I was really pressed for cash, not a if I could get into a 14 for a couple thousand more.
