A search on completed Ebay listings revealed that 2nd hand iphone 5c phones actually go for lower than iphone 5 of the same storage capacity. Even retailers such as Amazon and Gazelle buying iphones value the 5c less than the 5. Considering that both have the same internals and iphone 5's are older than 5c -- hence more likely to have less life left, I wonder why buyers still prefer the 5. Comparing 5, 5S and 6, the resale value of 5S is closer to that of 5. For example, max trade-in value at Gazelle for unlocked 16GB versions: 5: $65 5C: $45 5S: $80 6: $135 6S: $200 Iphone 6 is worth 32.5% less than 6S. Iphone 5S is worth 41% less than 6. Iphone 5 is worth 19% less than 5. Iphone 5C is worth less than 5! Prices go higher on Ebay but I do notice that the S version is more similar in pricing to its predecessor than successor. Iphone SE 64GB retail price dropped $50 within 6 months. In this sense, wouldn't it be best to skip the S/C models and upgrade to full versions?
