Just be aware (when musing materials) of the way the new fabric/leatherette stretches in each direction as that will affect just how good they look in situ. Find a material the behaves like the existing one for best results. Fabrics are generally tolerant of mistakes whereas vinyls and such are not as any incorrect holes will show. There is no reason why you can't make excellent replacements as long as you do things with care. There are a few videos on youtube that may encourage you and actually, learning to use a sewing machine is an excellent skill to have.
Perhaps start here?

But watch them all so you can absorb what he learnt along the way - particularly the seat centres as its documented in other videos that a section like that will come out shorter (classic mistake) and you have to calculate that. They're earlier seats but the principles are similar.
Also, if you have headrests you can fill them in to make solid ones. Oh, and buy really good scissors - it pays!
This photo is identical to the machine model I use - made by Hillman (yes the motor manufacturer). I swear it would stitch tin its that robust. The most use its had since new was just two hours as I knew its history. Just happened to be there when it was being disposed of. I'm 60% through doing mine. Hope to have them on later this year.
