I constantly see posts like this on the net, and please don't take offense, but you are not being intellectually honest. Load up a full size sedan with the same options as a loaded Mazda3 @$27K (2.5L S Grand Touring w/auto), and you will be looking at a car with an MSRP @15% higher than the Mazda3.
Examples:
Mazda6 = @$31K
Camry (2.5L) = @$31K
Fusion SE (2.0L) =@$33K
Accord (4cyl.) = @$31K
Sonata Limited = @$31K
Malibu = @$33K
In addition the Mazda3 is priced similar to other cars in the same segment with the same options.
Focus Titanium = @$27K
Cruze = @$27K
Civic= @$25K
Jetta = @$26K
Look at any segment, and a fully loaded model will bump up against the base trim of the next segment.
I think the real question is...
Why are you picking on and singling out the Mazda3?
