I'm a big fan of the arachnid model 3 covers, think I'll pick them up off AliExpress. They are also fully plastic so hopefully won't damage the original wheels underneath. Some good reviews on youtube and let's be real - all these sellers charging 200-300£/$/€ all just reselling them from AliExpress anyway
I bought a set of all weather mats from AliExpress when I picked up my original RWD M3 and the quality was unreal. Paid less than half the price as the Tesla versions and the like.
