Maybe so... Or maybe it sounds a whole lot greater than it actually entails. For example we can see he doesn't mention anything about claybar, so that could very well mean his definition of "wax" at least for this perticular package is simply a spray wax, which technically qualifies just fine considering the price.
So if all he really needs to do is:
Wash vehicle
Spray Wax as a drying aid
Clean wheels & tires [this is always standard procedure]
Clean interior and exterior windows [always standard procedure]
Vacuum [always standard procedure]
Shampoo [this could actually be done pretty half arse if the person is a corner cutting/budget/time type of detailer] Judging by the price of the package, I assume this is the quikest version of a "shampoo" there could be. Something like a quik foaming carpet cleaner on the matts and a quik run over the upholstery and he's done with the mini detail version of "shampoo"
Dress all leather & vinyl [you know how fast and Mickey Mouse they do this step at your local Hand Car Wash. A foam block applictator and 3min. later, he's done]
Rain X [I honestly don't even know how long this actually takes, but it can't take too long]
When it's all said and done, if done that way [and it smells like it is done that way based on what I see offered] It's really just a Glorified car wash @ $75 bucks a pop. And $75 bucks for just washing a car aint too bad. Not to mention he can upsell once he's in front of his customer, so part of this is a lure tactic just to get the juices flowing.
Same way CruzCarwash mentioned giving away 1 car wash per customer or something... Some people would say that's ridiculous, aint no way giving away a free wash is a good thing to do.. But it pays off for him on the rebound...
