Is this calculation based on an assumption a high resale value car have higher selling price? Try comparing price to price, then you'll get the effect of resale value. My accounting background says so.
But then again, when buying car, buy what u want, buy what u need, buy what u love. Not resale value. Haven't buy car already consider how much you can sell it? Srsly?
Yes, that is one of the many assumptions. My summary was "low RV is offset by low purchase price". It's obvious that when both cars have the same purchase price but one have lower RV, then there's no need calculate anything. But note that the calculation is based on historical figures thus like all other financial estimates, does not predict future values. A safe disclaimer :)
Like I said, the point of considering RV is to manage/minimize your liabilities/losses. Financial prudence is about managing both the positives (assets/gains) and negatives (liabilities/losses). Like it or not, RV is a real issue. Middle income buyers in developed countries also look at RV as a factor. You'll see reviewers mentioning RV as as plus/minus points.
By cruching some numbers, you can estimate if the loss is "substantial enough" to stop you from buying the car you're eyeing. The question is then, are you willing to take the financial loss considering what you gain (e.g. safer, better ride) from a lower RV car? I think having a rough figure is better than to brush of RV just like that. Unless you love the car so much, or too rich to care.
Maybe next time I'll try to calculate Merc vs. Volvo or Audi vs. Bimmer. In these cases, RV may even play a role even though buyers of the cars above are not exactly poor.
