Acura TsX till 2008 was Asian or european accord also known as Euro II accord.
Acura the luxury brand of Honda is available on North America and I believe no where else in Europe.
ILX is a compact/mid size sedan and no one will spend 26k plus tax for a compact so called luxury sedan. Yes for TSX which is mid size sedan I would go for.
At 26K price u can buy a VW Passat SE with sunroof and nav, with leather interior. Passat is a full size sedan. At mid size level at 26K you can buy a fully loaded VW Jetta SEL.
As of American brands at 24K you can get 2013 Ford Fusion altogether newly designed with much more options and features.
In nutshell ILX is nice looking car but expensive. Yes it has Acura logo on it which makes it a luxury..
