Quite a few years ago, Mitsubishi brought out the Carisma model (no carisma at all actually!) and a local taxi firm bought them in. After some had covered big mileages (200,000 +) they went to trade them in. Mitsubishi bought them at a premium price to strip down to see how well they had run. I thought they did that before launching but apparently "real world driving" - especially hard driving as a taxi was a better test bed.
