Can anyone recommed a good tint brand for mercedes e class? budget less than RM1.5K. Priorities is on the workmanship(assemble & disassemble) because i'm afraid on the wiring and the rattling noise that could be heard from the door. i don't expect a RM400k car to have this imperfection as my previous cars

i want to ask regarding a door visor. Mercedes-benz Malaysia offer me a free door visor. I know the advantages of it. But what are the disadvantages of it? Do original material or even factory fitted will counter the disadvantages that are typically associated with a door visor? Particularly in wind noise at high speed and aerodynamic?
