The good thing about a wrap is its removable. If you dont like it, simply remove.
If you take your time and have the assistance of another pair of hands you should be able to do this yourself as its a relatively easy panel being flat, apart from the shark fin.
I always thought cars with a pano roof looked great ( as it basically looks gloss black in most lights from the front and side across appx half the length of the roof ) and helps to give the illusion of a lower / sportier car. Plenty of ‘youtubers ‘ have conpleted this modification.
Wrapping the roof on your car ( if its a decent colour and wrap material ) should give the same illusion in my eyes and finish the look ( being across entire roof ). A decent 3M film isnt that much to purchase, just remember to buy a larger sheet than you think you need as you require excess to work with. Measure and line up and pre-cut antenna. If you have never wrapped anything, might be worth trialing on something smaller first before you waste material. Although not overly hard, there is an art to it to make it look A1, just be thankful the roof is a flat panel, as corners/ curves are a nightmare. You might need a heat source when applying , especially this time of year, as well as some lubricant ( to help manipulate for placement ), and best to complete inside if you can.
Really your question other than if, is how far , ie boot spoiler as well and inclusion of antenna. ?
Its your car at the end of the day , so its your choice.
