Iv'e been through what you are going through at the moment. I bought a nearly new Thema 16v back in 1994 and traded it in against an Alfa 166 in 1999.
I think it was the worst motoring decision I've ever made, talk about missing the car!! We had great times together, raised the kids with it, drove across Europe, had great holidays with it. It only took a few months of pining before it was replaced with a 1989 example to sit alongside the 166.
