The majority of Import cars take the award for holding their value better over time when compared with Domestics. We're not talking classic muscle cars, but regular daily drivers. You can still get $2,000 for a late 80's Civic hatch or CRX in good shape, what can you get for a Dodge Omni, Plymoth Colt of the same generation?
As for the interiors, I have yet to see an import who's plastic panels have turned to dust, but I quite frequently see GMs from the mid 80-early 90s doing this. The plastic paneling in the Impalas and Caprices had a grain stamped/cast in from the factory and over time it rots and you can literally scrape the grain off of the plastic piece with a finger nail. Also, I have NEVER seen a headliner fall in a Honda or Nissan but I frequently have to replace them in GMs and Fords. Try to remove a headliner from an 80s or even early 90s GM and see how many plastic clips you break in the process, then go try to find a replacement clip somewhere. I work in a shop the does mainly interior work so I can honestly say the import interiors are better designed than Domestics. A good example for the newer Fords is the dashes in mustangs all the way up to 1999. Instead of making a dash that was molded grey, or a 2 piece dash that had a black upper and grey lower, they cast a black dash and PAINTED the lower half grey. Guess what happens when something slightly rough and hard hits it? It scrathes the paint off exposing the black dash underneath. This to me was a poor design used in hopes of saving money. I haven't seen an import to date with a factory painted plastic dash.
