Is the TSX the closest to Euro-R Accord in US?
Nothing will be like the Accord Euro-R. But ... the new V6, six speed Accords are so fast, it's uncanny for a "family car"

Why Accord? Why not TSX if the range is so-so?
The TSX is a very sophisticated car. It's major downfall? It's an I4. The 06 Accord, V6, six speeds are much faster ... but remember, there's more to a car than just speed alone. You're buying the "Acura" badge ... you're buying a status symbol ... you don't get that with a "Honda".

Would you guys blame me for going with a Lancer Evo that costs possibly 1000-2000 more than a Accord V6 and TSX?
If speed is your only issue ... by all means, just get a Dodge SRT-4. $20K, 230hp off the lot. Up the turbo size, get some better cams, jack the boost, you'll be at the 270hp mark.

Remember, you're buying a Honda. These cars last forever. You buy a Mitsu or Subaru ... especially with how mechanical those cars are, you're going to be in for service quite a bit.
