Why would Honda need to make there parts cheaper and put out a parts CD, Honda builds a quality product and does not need to go to the length that Mitsubishi does with “cheap parts” for support. Along with a parts CD. Mitsubishi products are built so poorly they need all the support help can get.
PS I speak from experience My sister had a 1995 GST and by 30k they car rattled apart lucky that it was all covered under warranty at the time
