MG did this with the MG5.
They released it, then after only a few months, included lots of options for the same price !.
This infuriated the early customers ( as you would expect ).
Interesting to see if MG increases the price on the S5 X upgrade, because a full sky roof would be an expensive option if you could spec one ?.
VAG have played this game for years, but at a much slower rate.
Release a new model, equip it with the minimum level of features, then after about 12 months, start drip feeding extra equipment/ features for a similar price.
They do this for a couple of years, then facelift it with new lights etc.
After 5 years, new model and rinse and repeat

.
The sky roof is a nice feature, had it on both of our previous ZS EV’s, it brings a lot of light into the cabin, which gives you a feeling of more space.
When we sold our previous ZS EV it had the sky roof, on the later models, it was deleted by MG.
I told the dealer that the sky roof would sell the car for that very reason.
It sold in under 12 hours.
Every enquiry they had, they all asked if the car had the sky roof fitted ?.
Enough said on that subject.
