Not true on making money. Were talking Toyota's here, their not exactly considered to be classic just yet, along with that point most people would prefer to drive something they think looks better than to preserve the 'originality' of something. Yes grandpa style has been done but it still looks good, and yes it does give of view of being original even though in most cases its not.
Also keep in mind whitewalls were factory options back in the day, and being that they were quite unpopular her in Australia it means very few cars were rocking them when they came out.
I sold my KE20 for 10 times what i paid for it with wide 13" rims and whitewalls, not exactly original there...
