Neglected cars try to escape their owners by parking in tow zones or running away from their garages to join the demolition derby. Keep custody of your car with today's Groupon: for $17, you get an Ultimate punch card, good for seven washes, at Dolphin Car Wash in Thornton (a $35 value).

Eco-friendly chemicals, recycled water, and a friendly and efficient staff join forces to revivify vehicles at Dolphin Car Wash. A reclaiming system draws approximately 60% of water back in before cleaning and reusing it in future washes, while an arsenal of earth-friendly cleaning products purifies car exteriors and keeps the environment unharmed. Car lovers can take advantage of the complimentary vacuum, allowing for easy dirt, dust, and gold-plated Doritos removal. While not included with this Groupon, the on-site full-service oil-change center keeps hot rods purring like cats with engine-tummies.
