I used to have a ST220 aswell, loved that motor. After 5 years of owning it the fuel bills got to me too :lol:
You'll miss the low down power of the 3.0 and the noise (I had a K&N on mine :wub: ) but the accord is a slightly better car
I've been told by a lot of people it does.
I would tend to agree as the CC really does seem to 'floor it' when it comes to hills or when you resume it
Ive never been bothered and use it all the time lol
