Or maybe you're the lucky one in a million who managed to get a swift that is properly built!
I bought a dlx in feb 2015 bro.
Rattling is quite clear - need to be very slow and careful over bumps to ensure there is minimal noise.
Suspension is stiff - it really is. It gets bearable when driving around with passengers in the back seat. I have a lowered 96 civic as well and thats has more comfortable suspension.
