My drivers side A-pillar trim rattles when its very cold, but as soon as the car warms up it disappears. When I first picked it up, there was the odd creak from the passengers side somewhere, but that seems to have gone away.
Mind you, I'm coming from an Astra H which rattled, creaked and groaned like you wouldn't believe.
Had my Mk3 since April. have the occasional creaking from either the passenger A- pillar or the door card. Mine also seems to be more apparent when its cold. Otherwise no rattles or groans.
Had a 61 plate Mk2 FR 1.4 prior for about 18 months, seemed to be very solid, not 1 rattle or creak. Lovely car, but just disappointed with the petrol consumption and brittle ride. My Mk3 1.2TSI is so much more efficient while not lacking in power and gives a great blend of comfort and sportiness (despite the cheaper rear suspension)...its a great car.
