Wow.
Reading all the love and eulogising about mono.pur in this thread, it's time to inject a bit of reality.
If you don't spec mono,pur, the world won't stop spinning, and the sun will continue to rise in the morning.
If you do spec mono.pur, you'll have a bit more fake leather on the door handles and knee rests.
The insides of the door handles have hard un-textured plastic (mono.pur fake leather will cover this)
The part of the door handles that face you and armrests have soft touch textured plastic, identical to the dashboard (mono.pur fake leather will cover this)
The knee pads have hard un-textured plastic (mono.pur fake leather will cover this)
The door tops will still have scratchy textured hard plastic (mono.pur won't change this)
The door bins will still have scratchy textured hard plastic (these are especially nasty) (mono.pur won't change this)
If you have a spare £295, by all means spec it, it'll make the interior look less like a Golf.
If money is tight on options, spend the £295 on something else.
But to say that if you don't spec it, you'll regret it, is somewhat hyperbolic.
It's an A3 !!!!
