Are you talking about the ST150? Quite light in my opinion
I've since upgraded to a helix clutch and that's just as light as standard.

When I first got the car I stalled a few times as the flywheel is light as well... not really a problem but just for info in case it might be an issue with the knee for some reason.

Boot is okay for a small car, with the seats down I managed to get 4 wheels (with tyres) and 4 more tyres in. I took a picture of mine with the seats down for someone else on here but can't find it at the moment.
