As some may have seen in my earlier posts, I am narrowing down on getting a 612 as my daily driver year round. Sticky buttons and leather on dash pulling away, is this something one can expect to happen no mattter what, or is it a quality control issue? My guess is sticky buttons will happen over time no matter what, and leather issue depends on many factors. Long time 612 owners out there that never have either of these happen? Also, how are the air conditioner ps in Ferraris from these years?
