Curious to know everyone's experiences and views on these 'common' accessories - wind deflectors (also known as window rain guard, door visor, etc.) and mud guards (splash guards or mud flaps).
Do the deflectors really reduce noise, or add noise, etc., does lowering the window slightly with deflector actually help, etc.
Are mud guards still relevant now? Do they really reduce splashes/mud etc. or do they end up trapping them?
Looking to find MCFers' thoughts.
