Totally agree. It’s always a risk buying used. You have to be savvy on what to look for, research if there are common catastrophic problems, and hope the vehicle was maintained properly (any car needs more than just oil changes, including Toyota and Honda) and was not abused.
Generally you’re taking less of a risk buying new because of a good warranty and known history, but be sure to get a reliable car not something that will give lots of problems over its life. Plenty of data on which cars are best in that regard. Some makers are better than others on average but reliability can vary by model and model year, even.
Yes, cars depreciate in terms of resale value. That’s why we keep ours for 10-15 years. By then it doesn’t matter.
