Anything you buy, be it a laptop, mobile phone, TV or a car, there will always be a new model on the horizon. If you were concerned that there was something newer or better around the corner, then you would never buy anything.
With regards to Dacia, the only real change is the logo is going to change, so the grill has a new logo, the boot has a new badge and the logo on the wheel centres and steering wheel has changed. Yes, I can see your annoyance that your new car will not have the new logo on the front, but this new logo was not available when you ordered your car.
As I said earlier, the new logos will be applied to all cars ordered after the 16th of June, and you are well within your rights to cancel your order and reorder your car. However, if you do this you will need to order your car at the increased price, and you will go to the back of the order list so probably won't see your car until early 2023.
Even if the dealer had told you this in advance when you ordered the car, you would have still had to wait until the 16th of June to order the car and you would have still had to pay the new revised prices and pay an extra £1000.
I understand the frustration, I myself am waiting for my car to arrive and would have preferred the new badges. However, in my situation the car has increased by £800 and is currently being built, so I don't fancy having to pay extra and wait another six months for what is essentially a different logo on the car.
If there was an entirely new model coming out (think Sandero 2 to 3 like in 2020) then I would definitely have cancelled and ordered the new car, however in this situation I am happy to stick with what I have ordered as to me it is not worth cancelling and reordering for some different logos.
Out of interest they have updated the brochures now and I see the Stepway Essential no longer has the same seats as the rest of the Stepways, they are more like the seats in the Jogger Essential. Really hoping my car still has the original seats and they haven't changed them already. They have also made the wheel trims dark grey, I much prefer them in Silver.
After seeing the brochure, I am actually in the situation where I don't want the new car, I want the spec of the car when I ordered it.
