I don't think anyone would drive Micra entire decade by choice. I also think it is unlikely Micra would last that long.

Depreciation should be considered, as selling 4 year old Micra is bigger hit, than for example buying 4 year old Civic and selling it at 8 years. Plus, Civic is a much better car, so you are driving better car and spending less money on it.

Looking at auto-trader in Ontario, there are 2015 Micras for sale for $7,500. This is substantial depreciation when you factor in dealer fees (delivery and such) on top of sales price. So you can expect 30%+ depreciation in the first year. This is crazy bad.
