That is my concern: that it may not be cost-effective to repair. The car has 325,000 km on it, and is in nice shape cosmetically and mechanically. It has been a Vancouver, British Columbia car for most of its life, so has seen very little road salt. There has been a little surface rust on the sheet metal under the trim, which I touched up with paint. There is no other structural rust (other than the suspension cracks rusting where the paint has been breached). Maintenance is up to date, and the air conditioning has been converted. It would be a real pity to lose it.
