Purchased my P5 brand new in July 2003. Put about 18k miles/yr in highway commuting. No harsh driving, always take it slow and steady. All maintenance performed as required. Everything was great up til 110k miles. The overdrive gear in the automatic transmission failed and I had to replace the AT ($3000). I've had other Mazdas/Toyotas and nothing like this has ever happened (and shouldn't happen with only 110k mi). I'm not sure this is an isolated issue or systemic. Anyway, I really like this car, but reliability is in question. Probably my last Mazda.
Handling and fuel economy are excellent for this vehicle. It's really fun to drive and small enough to park anywhere. Good cargo room too.
