This is extreme. Knowing this Mazda would not cover this at all - and rightly so.
Why do you need to wash twice a week and wax? TWICE a week - do you get a lot of dirt? Do you park near sprinklers? Do you drive through mud / offroad / do you encounter salt etc? Twice a WEEK? Dude detailers on autopia do it once every 2 weeks and that seems extreme.
I washed my car -3 times in its first 14 months. Off late I have been lazy and gone to touchless but most importantly I have never used improper technique - I am not OCD about scratches as I know pretty well how to cure them.
So if its being washed so frequently - most likely its the guy who washed it. 700 times a year - 4 years - OMG = 2800 times. After owning my CX5 for 10 years I would not have more than 300 washes at max.
Final test - if the guy who washes it for you charges you atleast 50 bucks per week It comes to $10,000 dollars for 4 years - I might say its the fact that it was washed so many times is the issue. But if he charges a lot less than that - its a red flag.
Another test you can do is run your hand smoothly after he washes - your hand should flow without any resistance - if not his technique is flawed. this is most likely dirt ripping your clear coat. Wow TWICE A WEEK! what are you driving a Mazda Phantom?
