the TSX is older but more luxurious, it has more features and cheaper (I'm buying used)
The Honda Accord obviously is newer however, it has less features than the TSX, it is more expensive.

I have also done my work by reading reviews all over automobiles websites and I've come to a conclusion that the Honda Accord's owners have experience a lot of trouble in the rear braking. And the TSX's owners have very little problems and it is a solid car.

So, Which one should I buy and why? Thank you so much! Any help would be deeply appreciated! GBU
