 I bought this car new in 2003 with a 50k warranty.I complained several times about misfiring after 1 month and dealer never found the trouble.At 55k miles the trouble was found to be the Throttle Body.I wrote to Mazda and they said "Sorry, but we can't guarantee how long parts will last after warranty."After that the right control arm broke twice(most of my driving is on the highway).Now, after 8 yrs of meticulous maintenance the compression valves gave out and will cost more to repair than the car is worth.I wrote to Mazda, and again their response was, "Sorry, but we can not guarantee how long our cars will last."
