Snappy Auto Spa is a no frills, cheap and quick way to knock that layer of dust covering your car. For between 5 to 12 bucks, you can sit in your car while it's in neutral and get a pretty decent shine. It is right next door to a Sonic drive-in, so I suggest getting a slushee beforehand for the ride through the wash. In addition, they also have stations for you to do a self service job with the vacuum and detailing tools. Not a place to go for that full service detail job, but a great in between tune up.
