About the warning that Andymot gave I would agree. My son has learned about the various MX5 models. He himself drives an NA. The NB is constructed in a different way. In the NB, the longitudinal beams rust from the inside out. This requires extensive repairs. That's why you should take a close look at the longitudinal beams, preferably with an endoscope. The NA is not so susceptible here but should also get a closer look due to her age. But otherwise the NB is also a beautiful car to drive, just like the NA. In Germany at that time the MX5 was also called a Frisörauto. She did not deserve that negative description. It is a fully-fledged agile and very sporty car.
The article below describes very precisely what to look out for at the NB with photos. With Deepl.com or Google translator it is worth reading.
