Concrete Garage Floor

[Johnny7seven]

I've just had a new concrete floor laid butting up to the old one. The old one is a strip near the wall 16ft 7 long by 64 inches wide. And it's full of marks where it was originally laid and not properly smoothed off.
Now I could hire a concrete grinder to sort it out but it's not worth it. Was going to use my angle grinder to smooth off the ridges. Unless someone has a better and easier idea?

Screed over the whole lot?

Garage floor ? Leave it, it ain't hurting and is hardly a showhouse.

Good idea from Zacs... and OG always makes sense...
