Mohtaram Basit Sahib,
I would like to make myself clear. Please look at the first picture.
Here the dashboard is very 'straightish', I mean it doesn't have curves. The central console is very straight too having no curves. I'm talking about the area where the navigation screen and the fan vents are.
Now look at the second picture from a Mercedes C class. Look at the dashboard. It has all the beautiful curves which makes it look so attractive. Look at the central console. It too has all the curves making it look pretty, something missing in the corolla. I don't like the grey colour which one can get changed but this picture does have the curves I'm trying to demonstrate to you.
Now look at the third picture from a Mercedes S class which shows how beautiful an interior with a lighter colour looks. This is the beige colour I've been talking about.
Now look at the fourth picture from a Mercedes C class. This has a lighter colour and looks so beautiful.
Now look at the fifth picture. This is from a BMW 5 series. This is the interior with a lighter colour. See how beautiful it looks.
Compare it with the same car having a black interior in this sixth picture.. It doesn't look good at all. Now some people might like a black interior but remember more people like interiors with lighter colours. This is the reason why cars with light-coloured interiors fetch you more price as compared to those with a black colour.
I do like the current interior of the corolla. I will be able to comment on the upcoming 2014 Toyota Indus Corolla once I sit in it. I've the impression that the current interior is more curvy than the one which is shown in the picture of the 2014 Corolla. I hope they come up with an interior with a lighter colour, preferably a beige one and definitely not a black one.
Regards.
