2009 2dr Convertible 167-horsepower 2.0L I4
5-speed manual RWD
Good reliability history according to all research.
2008 2dr Convertible 158-horsepower 2.0L I4
6-speed shiftable automatic RWD
I only have about 15,000 miles so far. This car does not get driven in the winter because of road salt. Nothing has broken or needed repair yet.
2007 2dr Convertible 166-horsepower 2.0L I4
5-speed manual RWD
Knock on wood - the Miata has proven totally reliable so far. The maintenance bills are very low, and the Mazda dealer service is good.
2006 2dr Convertible 170-horsepower 2.0L I4
5-speed manual RWD
Has been 100% reliable over 6 years, 30,000 miles and two 2 month cross country trips.
2006 2dr Convertible 170-horsepower 2.0L I4
6-speed manual RWD
I haven ot had ANY problems with it. The car only goes to the mechanic for scheduled maintenance - what mroe can one say.
2006 2dr Convertible 170-horsepower 2.0L I4
6-speed manual RWD
Car had a major issue with its engine computer, fixed under warrantee. Other than that, no real issues.
2006 2dr Convertible 170-horsepower 2.0L I4
6-speed manual RWD
Flawless/bullet-proof drivetrain. Few gizmos and needless luxuries = fewer things to break. No need for repairs in 32k miles.
2006 2dr Convertible 170-horsepower 2.0L I4
6-speed manual RWD
its a mazda, it may be said to be too reliable, is there such a thing, this is my second masda mx-5, i ran my first one for 6 years, not one trip to the mazda garage
2006 2dr Convertible 170-horsepower 2.0L I4
6-speed manual RWD
I bought this car at about 40,000km and so far after 8,000km it has olny cost me gas, and 1 oil change that I will need to do this week.
2006 2dr Convertible 170-horsepower 2.0L I4
6-speed manual RWD
Mazda has closed the gap on Honda and Toyota. It hardly gets better than that. That plus the warranty and I have no worries.
2005 2dr Convertible turbocharged 178hp 1.8L I4
6-speed manual RWD
Never have had a single issue in the last 30,000 miles that I have put on the car in the last 8 months.
2004 2dr Convertible turbocharged 178hp 1.8L I4
6-speed manual RWD
Bulletproof reliability reputation with very few issues over the life of the car. Miatas with 200,000 miles on them are not uncommon.
2003 2dr Convertible 142-horsepower 1.8L I4
5-speed manual RWD
Except for a faulty engine part when it was brand new, I have never had to take this car into the dealership for service. 55,000 miles and I still love to drive it.
2003 2dr Convertible 142-horsepower 1.8L I4
6-speed manual RWD
Have had two (1996 and 2003) and have never had either one in the shop.
2003 2dr Convertible 142-horsepower 1.8L I4
6-speed manual RWD
Very low level of reported issues amongst my Miata driving peers. The engine is rock solid, and fairly simple to do relatively elementary work on yourself.
2002 2dr Convertible 142-horsepower 1.8L I4
6-speed manual RWD
I am now retired and have owned several brands of sports vehicles. I knew that the MX-5 would have the lowest maintenance costs.
2001 2dr Convertible 142-horsepower 1.8L I4
5-speed manual RWD
Among the most reliable series (certainly the first two) of mass-produced autos. Exceptionally reliable for convertibles.
2000 2dr Convertible 140-horsepower 1.8L I4
5-speed manual RWD
The car can go forever. Excellent quality, reliable, well built.
