I'm trying to fix up my parents old 01 Toyota sequoia. Gonna use it as our family vacation vehicle. 14mpg, but seats 8 with trunk space and a hitch cargo thingy. Split the gas between 6 ppl and plenty of room for everyone.

Plus there's actually room to work on the vehicle and no proprietary computer stuff that needs to be done at the dealer.

Don't abuse it and do all your own work. I keep most of my stuff running by inspecting frequently and doing repairs before it's an "oh shit will this get me to work" kind of failure. Also motorbikes are a bit different than cars, they run way closer to their mechanical maxes and are just lighter overall. They typically break down quicker.

Other than brakes, tires, oil, maybe a chain+sprocket when they start to look sad, what kind of repairs?

Maybe start looking at used Hondas?
