I would like to see some actual supporting data (mostly because I love to argue with people)
I will even go as far as to guess that if you did a comparison of "cost of ownership" and "fuel cost savings", a TDI would've saved you money based on the amount of driving you do (unless you do it all in the city, which is highly unlikely).
A TDI would've been cheaper to purchase and it would've been well suited to your mostly freeway use (yes, I'm assuming that based on your yearly milage), where it would tug along at low rpms not performing active regens.
Your Tesla's superior efficiency isn't that big of an improvement at constant freeway speeds, and it eats both electrons & rubber at accelerated rates during this kind of use..... it also cost considerably more to purchase....... not to mention additional costs (once again, assumed) like home rapid charger & install and the fact that you would've received additional "damages" from Dieselgate, and the "perceived" savings diminish even more......
I'll bet it's all brand placebo effect for you! (but it would be interesting to see a true comparison for sure)
I can tell you that I'm at 280k (km) on my '10, and I've only done routine spending (tires, pads, one TB, a sensor, a clamp, filter changes, etc) since buying it new. All other big ticket items have been covered under dieselgate (minimal stuff.... glow plugs, sensors, flaps, etc) and I'm still on original clutch...... oh and my '16s are almost "free" in comparison.
P.S. VW also gave me a little over $8k CAD back due to Dieselgate. (and I still have coverage on it for another 7 months\30k or so)
