Dealers will be very keen to sell such treatments – indeed, there are numerous complaints online about salesmen being just that bit *too* keen – as they can earn them a tidy three-figure profit. However, are they worth having?
Well, on the one hand, there’s no doubt that they do their job, and compared to the overall price of the car, they’re pretty cheap; but, on the other, you should remember that they only do a limited job. Yes, they’ll safeguard your paint against minor marks and fading, but there’s nothing they can do to stop the more major car park knocks and dents that are all too often part of modern motoring life.
Another way to look at it is that you can probably either do a similar job yourself using off-the-shelf products – if you have the time and inclination, of course – or you could get an independent car detailer to do the job for you, and quite possibly for less than the dealer wants to charge.
Alternatively, you could look at paint protection as something else to bargain over. Yes, it’s worth having, but probably not at the full price the dealer is trying to charge. They will have plenty of profit margin to eat into, so try and get them to do that. And, as with any step of the car-buying process, if they won’t play ball, just politely say ‘no.’
