I'm looking to build a 2 car detached garage. I currently have a single car garage in the location. Should I be pouring a new slab, or extending the existing one?

You could just form up and pour a few feet extension no problem. Rebar dowel or redhead anchor it to the existing slab.

More than likely there will be some amount of shifting over time. Hard to tell how much... Only b/c it almost impossible to EXACTLY replicate the subgrade prep to the existing slab. For myself I would have no problem doing it that way an call it good enough. For a customer, I'm not sure.... Depends how fussy you are.

^ This.

It seems that it's an old slab, and probably quite comfortable where it is. Make sure of the thickness, and dowel the **** out of it.

You're on to a good thing. Just know that bigger IS better. Most guys would say to build it as big as you can fit/afford/what the wife will let you, etc...

Like most things the prep takes more time and effort than the job.
You will need a base to match what you have for matching frost response.
If you are not an experienced concrete guy ask around to get a good local guy.
At that size it will be a "side job" for the guys after hours and on week ends.
But that is better than the very permanent results of a beginner’s mistakes.
Concrete looks simple, but it is backbreaking work that is as much an art as an science.

Check your local codes regarding building on a slab vs on skids. Code is probably a lot looser if you build on skids.

My brother in law built a couple of very small cabins, actually just a bedrooms, on his vacation property. Because they were built on skids and had no permanent electrical or plumbing hook ups, no inspections were required.
