As it is said in other threads, group N4 has been used by many as their first 4wd car. Many has also continued with it due to prices compared to R5 and WRC.
There is a hole in the system now that N4 and N4+{R4} is dying, and it needs to be filled!
How should a budget class 4wd car look like technically to become the logical stepstone from 2wd to 4wd?
