There are plenty of post 2003 vehicles with no surveillance and repairability issues. My 2014 Mitsubishi is basically a monkey wrechable shitbox with a hacked together Bluetooth headunit.

I decompiled the firmware for it and it's literally so poorly coded and designed that I'd be amazed if they managed to get anything out of it lol. It literally ships with emacs installed because whoever built it never pulled that package from the final build lmao
