Seat Covers are a personal choice. They liven up the interiors and protect the original seat fabric. If you do go in for them, get them done from a good brand who will do a professional job. Others who charge half the price and might give you ALMOST same quality material wont be able to do a good fitting which is absolutely essential for comfort.
Spoiler, again upto you. Definately looks good but why not put that money into good sunfilm to keep the car cool. Buy it later if you still feel like it
