I've owned both a 914 and a 944, using each as track and weekend toys. As such they were fine, but I would not want either one as a daily driver given the cost of parts and repair.

Since you are considering 2 seater sports cars as a daily driver might I suggest a Mazda Miata? Lots of them around to choose from, parts are readily available, and both the cars and parts are priced right. You also have the advantage of a wide range of after market go-fast items, an active club, and plenty of tech advice available.

Just a thought. I've never owned a Miata but have spent plenty of time on track with them and their owners who seem to enjoy them a great deal.
