or if you wanted to put the work into the car, why not get new weld in arches, looks bad, but not irreparable
Sorry, but poor advice, that corrosion is terminal, that shell will need floor pans, inner and outer sills, inner and outer wheel arches, almost certainly the rear shocker mounts rebuilding, its simply not worth it, for money, or safeties sake
When buying a Mk2, the condition of the shell is now everything! anything else can easily be replaced
OP, Cut and run from this car, don't get consumed by it...
