I had mine coated the day after picking it up with 4 coats of Ceramic Pro 9H and a top coat of Ceramic Pro Light (Gold Package w/ Lifetime Warranty). I also just had my wife's new 2016 Escape Titanium 2.0 coated with the same (along with having the interior coated with their plastic/leather/textile stuff). The stuff is amazing IMO. I've had the car about 6 months and you can still toss a rag on it and have it slide off like its covered in oil. I don't garage or cover it and drive it every day but IMO it looks like it was just detailed every time I wash it.
Prior to this I had my 2008 Evo GSR covered with a similar product, Opti-Coat, and believe me that stuff was amazing at the time, but the Ceramic Pro is even better. And before that I had tried various other waxes and sealants from Mothers to Zainos.....nothing compares. Light scratches and spider-webbing takes much, much longer to appear and washing is silly easy. Even now, I take off with the car covered in dew in the morning and it all rolls back like glass marbles and I end up with all the dust and dirt accumulated at the rear edges of the car. Sometimes I feel like I'm wasting my time actually washing the car because almost everything just sprays off with the initial rinse.
I'm crazy anal about having a great looking car but I used to hate spending hours every week to keep it that way. The Ceramic Pro makes it a breeze. If you can afford it, I'd do it. It costs a grip at first, but then you are paying the same as a cheap detail once a year (required for warranty and they polish it up and whatnot) and it always looks like a million bucks. You'd have to get a good detail at least twice a year to keep your car looking the same with regular sealant/wax and you still wouldn't have the same lever of protection.
