cant comment on a exgie, but i just bought a S1 elise
with the roof of it's slightly more awkward getting in and out, but not a problem and i had people getting in mine yesterdat that were 6ft tall
the roof on obviously comes off and makes getting in and out easier, the S1 exige doesn't come off.
noise in mine, is fine, wind noise picks up at around 70ish i reckon
fuel ecconmy is awesome
agreed straight line speed is slow compared to a cossie, but cornering is shocking

still getting used to that
