My drive way is about 25 years old, Its breaking up into rocks that were used in the mix. I have large pot holes. I don't have the money to break up and replace at this time. Is there any thing on the market that I can put on top of it.

You can repair the potholes and maybe seal the cracks. But the problem is you would be pouring over a unstable base if you try to do the whole driveway with just a topcoat. Since it would be on unstable footing it will crack all over again.
I worked in construction inspection for a state highway agency for a long time and I remember seeing presentations on a method of reconstructing badly deteriorated concrete roadways using a procedure called "Crack and Seat". I realize that you don't have access to the equipment shown on these slides but the pictures will help explain the concept. Also, you would have to have room to add a few inches of hot mix asphalt (hma)on top, amount to be determined by the hma contractor, and you may have to dig and build some transition aprons on both ends---drainage away fromgarage if applic?
The old concrete is first broken into max. size pieces (you would have to research for rec). A large roller is then used to seat the pieces (wire mesh and rebar would have to be cut if present.

It is a long shot and depends on several factors: 1) size of driveway, 2) feasibility of raising elevation sev. Inches, 3) can you do your own breaking with a rented jack hammer? 4) amount of rebar and/or mesh to contend with, and lastly the real biggies--Can you find a contractor willing to bring in large roller to seat the pieces and give a decent warranty on an overlay with hma?
I am just guessing but if you can connect all the dots here, this procedure would cost about half of a total concrete replacement or new sub base and courses of hma and should hold up. You don't say if there are drainage problems and/or settlement--if there is--this is not the answer!
Excavating and disposal add cost fast for total replacement.
