Terrible Herbst Self Serve Car Wash offers a convenient and affordable option for car owners. Customers appreciate the monthly plans, which provide unlimited washes and access to over 40 locations across Nevada, California, Utah, and Arizona. The plans include extra benefits like free air fresheners in various scents, a 32 oz cup, and the ability to wash up to twice a day, making it a good deal for families or frequent washers. The car wash features a self-serve setup with four stalls that are kept clean. While the water pressure is often described as not very strong, it is still usable for a quick rinse, and only a quarter is needed to start the water flow. Customers note that the equipment can be in rough shape, with some parts like the mitters barely moving and frames fading, indicating that the facility may need updates soon. The water compressor in one bay was reported to keep cutting off, causing water to dribble instead of spray, though this seems to be an isolated issue. Employees at the location are generally friendly and helpful. They often provide extra air fresheners, towels, and even a soda cup, enhancing the customer experience. Some customers mention that staff take extra time to scrub down vehicles before washing, which they appreciate. Overall, the wash offers good value, especially with the monthly plans, though some equipment maintenance and updates could improve the experience.
