Energy costs for me is $.23 here so that cuts into the savings a bit but should easily save $100-150 per month at the pump plus a few oil changes each year not to mention the joy and time added of never stopping at a gas stationIf you're driving 30k miles per year, this comparison gets even easier. The gas savings (especially over premium!) should be huge. Rough math at $3.50/gal premium, 30 mpg, and 250 Wh/mi at $0.15/kWh says over $2,000 per year in fuel savings.
FWIW, this is me. We got the 3 last year. Took it on a road trip (2500 miles to North Dakota, family of 4, car seats, backpacks, multiple suitcases, etc--all fit no problem).
My wife, uhh, liked it. So the plan was to replace her XC90 with the Y.
Then the X Raven refresh came, bringing that vehicle to the same range as the 3 LR RWD. And they made AP standard, and lowered the base price.
She now drives an X. So beware. The 3 can be a gateway drug. Granted, Colorado rebates sure help a lot, as did the full federal tax credit for the 3 and half for the X.
If you just use it for highway lane keeping, it's extremely solid and is a godsend in heavy traffic.
I think I would love the AP features personally suspect my wife will be a harder sell on them but will enjoy driving the car itself. Her previous car was a bmw 328xi manual and is now a 2018 X3 SUV and I know she misses the handling of the sedan
