I had a look at the other thread about this by silveri30uk then went for a browse around the Hyundai UK website and they are still claiming that the i30 Premium has the heater elements in the windscreen

From £15,200 - £17,000 on the road
As Style model, plus:
* 17" alloy wheels
* Automatic dimming rear view mirror
* Climate control
* Electric folding, wide angle door mirrors
* Front windscreen wiper de-icer
* Heated front seats
* Leather seat facings
* Rain sensor
* Reversing sensors
If they have told you that the web has been changed to reflect the alterations then not done it I would think you could create a noise about trades description and demand to know why yours does not have the feature which they advertise as standard on a Premium model.
Another thing I noticed was that the Premium now comes with leather FACINGS in the seats, not full leather like our ones.

It strikes me that this is a measure of the success of the i30, Hyundai have gained a reputation and are now content that they can "cheapen" the model since they effectively have a waiting list for owners. In my view though this short term gain could create a longer term damage, in my opinion the alterations made to the car since we purchased ours reduce it's appeal and would certainly be difficult to persuade me that I was getting the same level of car when I went to trade my higher specced Premium for a new one in a couple of years. I think that the moving of the USB port to a visible place is simply horrible, Hyundai have obviously noticed that Vauxhall have got away with it and followed suit. Things like this may only be small details but combined small things amount to a lot when the customer is parting with their hard earned.
