problems ith 307's
general things that need replacing on a 307 are -
ball joints (knocking sound when going round corners), drop links, door lock actuators (door not wanting to unlock, £200 a pair), rubber seal around front door, heater dial problems (where you adjust the position or how fast you want the air blowing in the car) & last but not least the dreaded particulate filter (cross your fingers and pray, £430 - £700)
