it depends on user/s: if single user then i recommend to save more than QR.20k and buy corolla but if a family is involved then go for Camry.
if it happened & u selected corolla then go for 1.8 coz it is in high demand when u want to sell and its performance is far better than 1.6
color is a reflection of the user's personality so u can select ur desired one without worrying abt heat coz heat will be there in all colors
