Mazda is not Toyota. Remember Amati? They have a history of bad decisions which is why they are #3 in Japan.
There is no justification to drop a $B to make an inline 6 at Toyota, None. Anyone who tried to convince the Board and CEO it was a good decision would be putting their career into the trash bin.
If you don't like the car don't buy it, but I would suggest you go for a drive first.
