I just bought a 2014 Prius v two with 144,000 miles on it. I hope I didn't make a mistake.

Here is my backstory.....
Hi everybody

Back in 2009 I wanted a Prius but we couldn't comfortably fit 3 people in the back seat- So we went with a Mercury Milan hybrid (same as a Ford Fusion). Well- 10 years later- Mercury went out of business( it was actually in 2010) , and the car was too small to drive comfortably from NJ to SC every month with 3 dogs. So we got a Honda Pilot for the hauling room which ended up being my preferred car to drive, and my hubby took over the hybrid Milan for his work car.
Then came Covid 19- and we were in SC at the time in our retirement house that we have yet to move into full time when the lockdown was ordered. We still have one foot in NJ. My son lives in that home when we are South. Hubby flies back and forth for work every month and I stay in SC most of the year and go home to NJ in the summers. Except for this year......Covid. Hubby is not flying- but driving back and forth due to Covid- and I was without a car for 2 weeks and was not very happy about it the first time he drove home alone.
So..... We bought a Prius v two- 2014 with 143,000 miles on it for me to drive around in SC! I love it. I test drove the regular Prius (private seller) and found it to be too small for me- I hit my head getting in and the windshield was just too small. We stopped at a dealership on the way home and stumbled on the Prius v. It had more miles than I wanted- tried to get one under 100,000 on it, but I took a chance and bought it

i'm hoping that the traction battery lasts another 100,000 miles.
I drove the Mercury Milan for about 9 years and didn't change my driving style. I didn't know I had to- to get better mileage. So now I have googled and youtubed, learned about Pulse, Glide, and coast, what the B on the shifter means, breaking slowly and coasting, and learned to NEVER run out of gas, and if you do, pull over and get gas delivered- at least 3 gallons worth or get a tow. Any other thoughts for new owners? Thanks for reading
