I would put a small sub panel in the garage, if only to keep you from having to run in the house in case of blown circuit or some emergency. This will give you more flexibility in the future and additional safety. In the event something went wrong there is the potential to overheat/damage the buried wire before the circuit would pop. With a subpanel the buried line would be protected and the damage would be contained to the garage....This would be and extreme case, but ya never know.
For example I have a 60 amp breaker in my main panel, from there I have 8AWG leads going 125' (mostly buried, all in electrical conduit) to the subpanel in my garage. The main breaker in the sub panel is only 50 amps, and then I have my circuits broken down from there, the idea being that if something went really wrong, the subpanel itself would trip before the buried run overheated enough to trip the breaker on the main panel. Probably overkill, but fire sucks.....
this may not even be the best route, but running a 220V line 75' to receptacle to a 5' extension cord doesn't sound a whole lot different than a 80' extension cord, even with the 8/2 to 10/2??? Especially if ya start running a high demand tool like a D/A or any autobody tool which will keep the compressor working for extended periods....
Do your homework.....
