Well it just so happens that my dad has an 08 Accord Euro...and I obviously have an Aurion ZR6.
Without a shadow of a doubt, the Aurion has ALOT more balls and is a heck of a lot quicker off the line. But we all know why that is....
Secondly, I have to say, I actually prefer the interior of the Aurion over the interior of the Accord Euro. Yes the Aurion's interior may be simple, but that's exactly why I like it! I jump in to dads Euro (he has the luxury version) and I'm surrounded by knobs and buttons. It's all too confusing and just looks far too cluttered IMO. Yes the interior feels a bit more solid in the Euro, but at the end of the day, like every other car out on the market, it's full of plastic!
Plus, the torque steer is pathetic in the Euro compared to the Aurion. Toyota have done a really good job in regards to reducing the torque steer.
Hands down, I would buy an Aurion over the Euro anyday!
