Been using a brand new Mazda 6, 2 L for the past three and half years. Every time I look at it, my heart skips a beat ?. Spacious and comfortable. The road noise is a bit high. Responsive and powerful. Loads of cargo space. Reliability is its strongest suit. Not a single issue so far. Changed break pads once through agents. Frequently get mistaken for a Benz and even once for a Tesla! My point is Mazda 6 is a large family car, with sports sedan creds which punches far above its weight.
Premios on the other hand are, well, good cars. Or so my car dealer friend tells me.
