If you can stretch your budget for a CS2,
and if i was in your situation of choosing between a EK3 and a CS2 i would go for a CS2
power wise the CS2 is more balanced and even a Auto gives u 10+ on fuel (please don't expect more than 12)
i don't know about others, but i have found the CS2 is a bit more comfortable and quieter compared to a EK3 (but mind you the I've driven is a 1997 or so)
so basicaly.
if its between EK3 and CS1.go for a Vtec EK3
if its between EK3 and CS2 go for the CS2
This is just my opinopn. Good luck on your buy mate.
