Took one for a test drive today out of curiosity. Noted:
Better visibility than the Civic
Nice interior feel.
A rear wiper.
Full 'space-roof' (I can see why it couldn't be done on the Civic)
Nice and airy
Didn't roll too badly, although i wasn't really throwing around too much
Civic steering wheel
Civic-ish display computer
Quiet engine at normal revs
Doesn't sound as rough as iDSI at high revs
Possibly less wind noise than Civic
Better Magic Seat design than MkI
Not so Nice:
1.4 (1339) VTEC a little weedy below 3500RPM, compared with 1.8 in my ES
Gear change throw quite long
Slightly odd feel to the handbrake
Not half as funky as Civic
Light steering (not toooo vague though)
Shift indicator is a 'enjoying your drive' indicator!
No 'heads up' speedo
No devil/angel lights either
As I've decided I don't need a high performance car, I'm quite tempted. I just need the dealer to make me a decent offer!
