Thanks to everyone for the replies. I've been a long time lurker (going on 5+ years) of the Lemons scene, so I understand what you're all saying. We fully intend on running an honest $500 car. If that means starting with an $800 price tag, but two cars we can sell stuff off of then that's fine with us. We will have documentation for the BS inspection and will bring some local brews as an offering just to be safe.
We're under no illusion that we'll be fast. The current plan is to focus on reliability (increase oil capacity, improve cooling for the water and oil, add warning lights, add a rev-limiter for the first race or two, etc), do some minor suspension work (box the wishbones, cut the springs and/or get stiffer junkyard springs, etc) and come up with a decent theme (we have two in mind currently). We're not touching the motor and are not going to buy any fancy suspension bits.

91 in my driveway:
The 88 made the 20 mile drive home without any problems, but it's kinda ugly and a ton of the creature comforts don't work. This is its better end:
As they sat when we picked them up. The 91 is in the foreground and is on the toe dolly:
