It's one of the biggest car washes on the west coast, and (to my knowledge), the single tunnel Sonny's has sold with the most equipment in it.

Costco opened their 10th and largest car wash when they built their Torrance warehouse store. It has a massive 200' Sonny's conveyor, loaded with friction equipment. The wash tunnel has 3 sets of SF72 wraps, 2 TOP2k14 top brushes, SFM901 and SFM807 mitters, TBG300 Bison and Ninja wheel brushes, 2 sets of SF50 side washers, 2 sets of SFB21 rocker brushes, 2 sets of SFB28 rocker brushes, a 6 manifold OMNI, turbo wheel blasters, a 16 producer drying system, and Tire Seal machines. Costco's car washes use NCS CleanTouch and CSI chemicals, and the car wash service includes double wheel cleaning, Ceramic Punch, and tire shine.
