I'm not sure which is the best sub-forum for my question, so I'll try here.

I'm looking for automobile binary files for reverse engineering. For no particular purpose, just to practice my static analysis skills.
I was wondering if there is an option somewhere to get actual automotive elf files, maybe even with symbols, instead of the common .bin/.hex files.
Even something very old could be helpful. And I really don't core which electronic control unit is it comes from - as long it's something that installed on a microcontroller on a vehicle.

I would appreciate any ideas or help to get such files.

Thanks!
