How much does it cost to replace the brake lines in a Chevrolet Chevelle?

I’ve driven a Tesla for the past decade, so I haven’t filled a tank of gas in at least that long. Unfortunately, my electric ride is in the shop, and since I need a car, I’ve been forced to borrow one of my brother’s spare cars. Besides the ignominy and humiliation of having to drive a gasoline-fueled car again, I can’t even figure out how to open the gas tank! I’ve been sitting at the gas station for an hour and people are starting to wonder what I’m doing. How do I open the gas tank on a 2000 Toyota Avalon?

My mechanic told me that I would need to get the transmission replaced in my 2013 Honda Accord, and then he quoted me a pretty ridiculous price. Or at least it seemed ridiculous to me. But I don’t know much about this stuff. What should A transmission replacement cost for that type of car?

I know many dealerships are notoriously closed on Sundays. It’s a day of rest for many, but it’s also usually my only day off. That’s why it would be the best day for me to go buy a vehicle. Can you buy a car on Sunday anywhere?
