Those numbers are a bit of a joke.
First off, some of the numbers (both ways) are ridiculous. It says $3300/year to insure 1 car? I pay $1920 per year to insure an RS4 and an A4 Avant
Second off, the maintenance and repairs are MUCH higher for the petrol engine, however the Bluetec vehicles tend to cost quite a bit more to maintain and repair, so I’m not sure why that’s so far off.
Finally…and this is all that matters…$11,000 EXTRA depreciation on the petrol version. That’s absurd.
If you didn’t question any of these things when you looked at it, I’d be a bit surprised. Perhaps you missed them.
So, to summarize - the numbers overall are BS, and the main differentiators (repairs/maintenance and depreciation) are erroneously skewed in the bluetec’s favour when reality shows the opposite.
