I have a 2010 Toyota my wife and I love to drive. It seems to drive fine but we took it in for brakes and found the ABS has issues (1k part + 800 labor, ouch!) then they confirmed we had some issues with some axles that need replacing and a few other misc things I wouldn't argue about. Altogether the bill is 3k, for a car that's currently worth 3k in trade-in. I'm certain the work needs to be done (consensus with 3 mechanics, and I know a bit about cars, just don't have a garage nor the time to do this myself).
Obviously it's hard to get a replacement car now at a decent price, and we'd probably be spending 35k+ easily for a like car. This work is being done at an indy shop and I was quoted 5k for the same work at the dealer
The car has a timing chain and other wear parts were taken care of not long ago (spark plugs, valve cover gasket, spark plug gaskets, intake air sensor, new tires, new brakes), so I'm hoping the repairs would last another year at least? The car has 150k miles on it and otherwise drives well.
Should we save the 3k for a new car now, or spend the money and repair? I am not sure what to do

Please help..how do you decide? It's a pretty big bill and while I can afford a new car, I don't want to unnecessarily buy one. Covid and supply chain issues have really made this decision difficult. If this were pre-covid we'd probably just be at the dealership or looking at some lightly used cars to replace it with.
