Absolutely.

I aim always driving with a big smile. Especialy when i look at the fuelgauge, how much km there still are in the tank

The lower highway speed is compensated by leaving 5 minutes earlyer.

All the stress of driving to work is gone.
I aim a lot happier now.
No more stress, like, aaahrrrggg that dude in front of me is driving to slow (5a10km/h under the speedlimit that is 3a6mph)

Hey, and if it goes like this. The payback is a little more then a full year. I can live with that

Even if it takes 2 full years to have a zero. It is still worth it.
I aim planning on driving this car for at least another 4 years. Then it will have around 250000km on the clock. Maybe i will drive it 6 years = until 300000km...

I dont know. It depends on the anual car inspection. If it keeps passing without costing to much monney. Then i will still drive it.
