Wow, that is a major change of direction. Before you make such a change I would suggest you actually test drive each of the cars you're thinking of to see if they really suit you. The Mazda MX-5 is a two-seater and not very practical for instance. It's hard to advise you because we don't anything about what you want from the car you buy. If it was me I would probably buy the MX-5, I would have no problem with a two-seater.
