Hi Stevie,
Have had my last two cars treated and have thought it worthwhile in the long term. I also had SWMBO's Toyota Yaris ceramic coated, and the water runs off, and all it needs is drying.
My current car is now 11 years old nd a good wax every three months is all it needs. I say go for it, but some may disagree -- de gustibus etc etc.
Regards,
Peter
