What’s the best MX5? Depending who you ask you will get a variety of responses.
What’s important to you? If you have never owned an mx5 the older models have no sentimental value and to be honest as a stock car they are poor in regards to safety and performance if compared to an NC or ND.
However before buying anything I’d go for a test drive and figure out what you want yourself rather than taking someone else’s opinion.
Although I’d want to have popup headlights again the sensible in me would look the wallet and buy either an NC or ND.
