It's been over three months since I last washed my car and I wasn't really sure if there was still the original colored paint under the layer of dust and crud that's accumulated. To my defense, I only drive about once a week, so car maintenance isn't a high priority. The Arizona Car Wash Company (formerly Weiss Guys) did a great job of getting my car back to looking like a road-legal vehicle.
Although I thought the price was high ($11.99) they did take $2 off and offered a punch-card--after 7 car washes the next wash is free. Also, on the back of the Fry's receipts there's a deal for a $6.99 wash that I'll use on my next trip.
And, in case you were wondering, my car is grey under all the dust. Amazing.
