I can't open your sheet right now, but I did the same prior to making my purchase.
Each situation is different. For me, we ran a 8 year scenario for 150,000 miles with a residual value of $0. We also ran a 5 year scenario good at 60,000 miles using KBB for residual values for a number of cars.
For Tesla, we used their prepaid service plans as a price point. For all other makes, we included any initial included maintenance (BMW, Jaguar, Toyota, etc.) and actually called to get service estimates on major intervals.
I'm in the US, but a MS 60D for my situation came out to be the same exact cost per mile as a Toyota Sienna or Toyota Highlander. It was also cheaper than a Nissan Maxima, Acura RDX, Jaguar XE, Ford Explorer, Hyundai Genensis AWD, Lexus GS350 AWD, Cadillac CTS AWD.
Having owned at half a dozen Subaru's, I can say it will won't come close in terms of cost of ownership when compared to any model using a 2.0/2.5i with a CVT over a 5 year span. In the US, the residual values, included 3 year maintenance, and low fuel consumption make it tough to beat. Even if you extend into a 8 year/150,000 miles it'll be tough. If you have a turbo version or a version that requires premium gas, utilizes their timing belt instead of chain, or is lower in reliability; then those numbers skew and you will break even eventually with the time frame based on how lucky you are or aren't.
