After washing it I’ve just booked it in for a valet and ceramic coat.
It’s the first time I’ve ever ever paid for anything like this on my cars so I’m hoping it’s worth it
It will depend on a few things. The prep done and the products used by your detailer and also how well you maintain it afterwards.
If you're planning to get it done and then take it to the local car wash every week, then you won't see what the fuss is about after a couple of months and I wouldn't bother spending the cash in the first place. Maintain it properly with good washing technique and the right products and you will one hundred percent see the difference in how clean your car is, and remains, compared to most cars on the road.
Except the top of the rear bumper. That gets manky real fast, no matter how well you try to keep it clean.
