Modern electronics would be screwed. Chainsaws, and mechanical tools that are of the like should be fine. Best I can reccomend, is get an older vehicle and start working on it. Get it up to snuff since it has zero electronics it should be fine.

Bottom line, if an emp hits, Im not worried about GPS and such, because that more than likely is already down due to the amount of electronics on a satellite, so they will more than likely be dropping fast anyways. If they arent down, then they will be soon because NASA more than likely wont be feeding corrections into satellites to keep them aloft. Best bet is get a compass, some maps, and start reacquainting yourself with land navigation old style/
