My quandary is that I have been thinking about a full frame but this sounds like to good a deal to pass up. The gentleman is local and retired as I am and he wanting a full frame also. We both agree that we do not need another body but try to justify by why not at our age. I do like to shoot wild life and birds some family and friends as well. I have three capable bodies already the newest being 60d. Your thoughts appreciated.

First, for your purposes, you really don't need a full frame camera. In fact, for wildlife and birds, a crop sensor camera is a better choice in a lot of ways.
7D has essentially the same image capabilities as you 60D. Both use basically the same 18MP sensor. The 60D is actually slightly newer and it's images might seem a little sharper. But that's only because Canon kind of got carried away with the low-pass filter on the 7D, and they backed off on that a little with 60D. With a little more sharpening, the 7D can pretty much match the 60D image-for-image.
Besides that, in a lot of ways 7D is more camera than 60D. More advanced 19-point autofocus, faster frame rate, better build with more sealing against dust and moisture, 100% viewfinder, Micro Focus Adjust, more direct control of many functions and more customizability. 7500 clicks is just barely broken in... 7D is rated for 150,000 clicks. I have two that have taken 125,000 each and are still working great (60D is rated for 100,000 clicks).
Some things it lacks that 60D has are the articulated LCD screen and some of the more automated modes are less accessible. 7D is designed for more advanced photographers who most likely want to control their own camera. Instead of "Scene Modes" on the mode dial, it has user-definable custom modes, for example. The 7D's 19-point AF system is more complex and it can be a bit more challenging to learn to use well... but it's very capable for action shooting once you get accustomed to it. A slightly dumbed down version of the 7D's AF system is being used in the 70D and T6s/T6i models. 80D is getting an entirely new AF system (45-point). 7D Mark II got it's own unique 65-point AF system.
In a sense, 7D sort of replaced the 1D Mark IV as a crop sensor sports/action camera, at far lower price. Canon no longer makes an APS-H 1D series model. They've phased that out in favor of the higher specification APS-C models (7D-series) and full frame 1DX, now the recently announced 1DX Mark II.
Like 1D-series, 7D uses dual Digic 4 image processors and a discrete chip running the AF system (in comparison, your 60D uses a single Digic 4 processor for everything). 7D uses a shutter release that's inherited from 1D series, too... that makes for shorter shutter lag and is better sealed and more durable that 60/50/40D, which is good for sports/action/wildlife shooters.
You didn't mention what lenses you have with your current cameras, but any EF-S or crop only are fully usable on the 7D... would not be usable at all on a full frame camera.
Among FF cameras, the 6D that's sells for about $1250-1300 is very similar to 60D control layout and is the least expensive. It's 11-point AF system is similar to 60D's, except that the 6D's center AF point is able to focus in a bit lower light. However that's the FF camera's only cross-type AF-point. All 9 points in your 60D are cross type. So, the 6D's AF is both slightly less capable than your camera's in some respects, though it's a little more capable in others.
You'd have to spend around $2500 to get as good sports/action AF system in a full frame camera, with the 5D Mark III (61-point, but otherwise similar to 7D's or 7DII's). Even so, for a lot of sports action shooting - and especially wildlife and birds - a crop sensor camera still might be preferable for its "free 1.6X teleconverter" effect.
I'd say go for it. $400 is a really good price for a 7D. Do plan to spend some time learning to use the AF well, but there's now a lot of info online and some good books about it. Also be prepared that the 7D is larger and heavier than your 60D (in fact 7D and 7DII are the same size and weight as a full frame 5DII or 5DIII).
