Yes, I'm going to miss the BMW. In a perfect world I'd keep it just because I think it has potential as a future "classic" because it was the last BMW to feature a naturally aspirated engine among other qualities. The 130i with the inline-6 is probably going to be a collectors car in the future blending in that N/A engine, RWD and 50:50 weight balance into a fantastic driving package.
The A-Class has come a long way. The first generation was technically innovative at the expense of being ugly and cheap. The second generation saw an improvement in quality and luxury but wasn't good looking. The third generation traded in innovation for style (and sight-robbing A-pillars!) with some new technology. The four generation has it all; style, quality, luxury and innovation [technology]. The A-Class is finally a
real Mercedes.
