Route 41 Car Wash is undoubtedly the best car wash in this area. For less than the price of a self serve wash (about $2 less!), you can have your car's exterior washed here. They can accommodate big vans/trucks here, and can even perform oil changes and detailing! Every service they offer is reasonably priced. However, the convenience store where you pay is another story. The items there are highly overpriced, and the lunch part of the "lunch & wash deal" does not seem fresh nor worth the money.
If you choose to visit this wash, be sure to look in Clipper Magazine or their website for coupons. Full price for a basic exterior wash is around $5, but coupons can take as much as half off.
Tip: Certain weekdays have 1/2 off discounts for men, ladies, and/or seniors.
NOTE: They are in Cherry Hill, NJ 08003 not Haddonfield.
