“Old beat up” need not apply to a mid 2000s vehicle. I bought a 2006 Toyota in 2015 for $6k and it’s still looking just fine and is not beat up or rusty.

Make a burglar have to take time, make noise and be seen. Make it seem like someone or a dog is home Make your treasure seem less desirable. Examples: beefy strike plates, strategic security film, fake cameras, see-through fences, less places to hide,some crappy looking stuff outside, keep a talk radio on loud so it can be heard from outside the front door. Huge sog bowl near back door (even if you don’t have one). Etc etc

Read books by them, but better to read books of the wise instead. Usually not the same.
