Since car was released not so long ago, I am fairly sure that this is an issue with the CRAN metadata, similar to what I (and many others) see for newly released packages: https://stat.ethz.ch/pipermail/r-sig-mac/2026-February/015335.html
I wrote some code to show the packages for which the metadata is inconsistent: https://gist.github.com/gaborcsardi/797472e42b43d2f938f852614f2a170f (Update the URL for a different arch or R version.) Seems like car should be fine now, assuming this already propagated to your mirror. FWIW AFAIR all RStudio does is calling install.packages() so if you see a 404 there, it is unlikely that it is a problem with RStudio. Nevertheless I agree that it is always a good idea to test your code in a plain R console.
