I have been driving a 1991 Miata everyday for the past 4-years. I bought it with 60k actual miles and it just turned 90k last week. It is a great car for L.A. traffic. I love it!
I bought a new 2016 MX-5 (Miata) ND with the club package (Brembo brakes, forged BBS wheels, Bilstein shocks and a limited-slip differential) on the last day of November 2016. Overall, I like the 1991 better than the new car, although the new car is faster.
In fact, the new MX-5 sits in the garage most of the time and I recently decided to sell it (it has less than 4k miles on it!). I realized I only need my 2011 Elise SC for weekends and the NA Miata for everyday and I'll be happy!
Good luck with your new Miata!
