Depends on what your "day" looks like. In short, the Maserati will make as good of a daily driver as any other 8 year old sporty car.
IMHO, these cars make awesome daily drivers if your commute is on nice backroads where you can let the horses run. On the other hand, if your commute is city based, I'd stick with a BMW for daily transportation duty. I don't think these cars are bad in traffic, it just isn't where they shine.
It has a LOT to do with where you are. It makes an awesome year-round DD in California but will kick your ass in the North East. I have an Audi A8 as my bad weather car because quite honestly, I don't want to subject my baby to snow, ice or torrential rains.
