Our 1996 Corolla requires a replacement rear box on the exhaust at a cost of nearly £400 for the box plus labour. It is mainly used as a runabout to go into town. The car now sells for more than what we paid for it s/h in 2012 as similar models selling for neatly £1000. It is very reliable and we have spent very little on it except for a rear box several years ago, battery and tyres. OH has suggested selling it and buying another car, but then you never know what you will get buying second hand. I think I would rather pay to have the rear box replaced.
