My car is already 3 years although the interior is still doing fine, I am already itching to totally changed it. Maybe I am already totally bored on its current appearance.

How often do you change your car interior? :popcorn:

I'm in the business and can tell you that some enthusiasts can change their interior (everything I mean.. ) once a year! Of course its all personal preference and financial situation (some people just have too much money). I say if you're getting sick of it, and you have the cash, why not?

Change when it's the time. Of course the cost is a point to care about. Change a new set of seat cover maybe will refresh the interior.

I change my Car Interior twice in a year.
And firstly, I give preference to change the tyres because without good tyres your car can't working,and may be it will give your car refresh the interior.
I think to change the car interior its all depend on Car condition.If your car condition is very bad then you can change your car interior once in a year or its good then twice or thrice in a year........:)
