How’s it going, recently bought an 2006 Impreza RX estate (2.0 manual) as my first car, so naturally thought I’d post here. I know the usual stuff (rust spots on wheel arches, engine bay - which this car has none) anything else that people can tell me about these belters? Not too fast, but an amazing car to drive. i have recently noticed a pin-sized bit of rust on the offside back door , is this anything to worry about and is there anything I should do to combat that before it grows? Everything else is in great condition (other than brakes) cheers!
