My 159 is now 7.5 yrs old, i've owned it for 6.5 of those years.
I finally got the itch to change it. Before that I had a 3 series bmw. I got the itch to change that 3 weeks after getting it.
What I can't find anywhere else is the wrap-around aluminium dash, I love it. I do a lot of miles, and it just feels right sitting in the Alfa.
I keep waiting for my M32 gearbox, which I am told is made of glass, to go, but there is no sign of it. Once that starts to go, then maybe I'll have to change. But I have not seen a single car that looks so inviting to sit in for 5 hours on the motorway as the 159. Hopefully my glass M32 gearbox will last a while longer yet. 81k miles and counting.
