Price development of the MX5 through introduction of the changemark

Hi, play for some time with ever-more concrete thoughts to buy me an MX5 – if the change-sign is actually coming as planned next summer. I set myself a rather tight budget (max. 350€), which does not bother my plans, because I am looking for the puristic of the first generation. I look with concern into the future when our cars walk and patronize us with lane change, lane hold or fatigue assistant. Unfortunately I watch the MX5 mark. t only a short time ago, so have no idea how the price level of the last years has changed. Are the NAs more price-stable, lose or gain value? How pronounced is the cult factor? Are the NAs more seen as great boxes, or are they now in cult status and gain value? What is your assessment regarding the change sign? Does the price rise? Are older MX5 desired or will people rather look into the price segment 7,500 to 10,000€ ? What I have already read here in the forum leaves the impression that there are some experts and MX5 connoisseurs. I would be pleased if you would give an assessment of the market situation! vg
