What should I look for in a used Mazda MX-5?

What are the most common problems with a used Mazda MX-5?

When viewing a used car, always follow our used car buying checklist.

The Mazda MX-5 was praised when it came out for having a leak-free roof – something that sports cars haven't always been able to boast about over the years. If you test drive an MX-5 and want to check the roof for leaks, head to an automatic car wash and put the car through a cycle.

Being small, it should be easy to park. But, because the driver sits quite low, low bollards or walls can be overlooked, and rear parking sensors aren’t standard unless you get the Sport Nav. Check the bumpers for scrapes because it can be costly to put paint damage right.
