"WANTING the problem?" Dude, what's with you? Sorry, but toting around an assault rifle in my driveway is NOT something I'd consider an "alterative" - that's just a good way to get the cops called on me and start a whole mess of legal problems that I don't need and can't afford. (Besides, I don't even own a gun to begin with.)
There's a lot of good suggestions, given, but a lot of them don't necessarily apply to the given situation because this isn't a standard HOUSE-house kind of Homeowner's Association situation I'm stuck in, here; if it were, I would GLADLY just tell that old hag on her golf cart to stick it, but as it is, I'm kind of stuck where I'm at and I need to find a viable solution that's reasonable and within my financial reach. (The garage renting thing appeals most, but I don't know of any in the area, and I've already called around about the storage shed things and they're a no-go for auto repair with their rules.)
This situation is really irking me because I'm already a bit overdue for oil changes on both vehicles, and the exhaust needs to be addressed relatively soon before the temperatures make it too chilly to deal with even during the day. Anyone in the Phoenix area know of any places off hand I could try out? At this point, I could even make do without the use of an electrical outlet (just hafta invest in a couple cordless tools), I just need a place to fool around with my car and not get ticketed/fined or yelled at for turning a couple of wrenches.
