A Little Interior Fix Up

I purchased a 2007 EB Max a month or so ago and it had a few issues inside that I've been slowly working on. I wish I had taken some before pics but didn't think that far ahead. I had to clean the heck out of her as she'd been neglected but the bones were good. The dash was the worst, those silver colour pillars were beat up and a lot of black showing through so it was PlastiDip time. First I tried Black, but it was too much, next I tried the gun metal which was ok but still not right (if you're unfamiliar with dip it just peels right off) but then I had an epiphany. I was staring at everything scratching my head and I realized that with my EB seats being blk/tan I could get away with doing it on the dash and plasti dip does have a tan colour in their camo line. I also am not a fan of the orangey/redish fake wood pieces so I removed them and painted flat black and installed an overlay kit from ebay. I painted black first because the overlays don't cover everything and I didn't want the wood coming through.
The other main thing I had to do was the driver seat, it had the normal ford hole that the previous owner stapled and duct taped. I took it to a local upholstery guy and a few hours later good as new.
Also done a bunch of little things, heat/cool seats needed a new module and the power mirrors needed a new switch and fixed the 3rd row headrest that wouldn't fold.
I am sure there'll be lots more to come (I hate the running boards), I've attached a few pics as well.

What did the upholstery shop want to do the bottom left side of the drivers seat? Is it leather?

Yes it is leather and I'm in Canada so a little difference in currency but it would work out to about $175USD. A cheap seat cover would work but the rest of the leather in the entire thing was mint so I opted to spend a little more. Also with seat covers the heated/cooled seats don't work so great
