It's not about Airtrek but more in general. My Airtrek comes with clear windows (local USF car), but I've tinted the rear doors, rear side panel and rear windscreen 75% tint. Using it for 4 years now, no problems...
yet again my engine has failed..have a 4g63 and when opened up the head found 2 pistons cracked and 1 fella rusted on top..on cylinder 3....
a nasty scratch was noted inside the blok...arrrrrr!!!
