The Mazda MX-5 has pretty much set the standard for small roadsters. It has good all-around performance, and has always been one of the best-selling convertibles on the market. Being so small, the equipped 2.0-liter, four-cylinder engine lets the MX-5 sprint to 60 mph in 6.5 seconds and hit a top speed of 130 mph. That’s not bad, but is the car actually safe? According to the European New Car Assessment Program (NCAP), the MX-5 is reasonably safe, but not as safe as it could be. NCAP gave it four out of five stars, but what does that really mean?
