Hmm, sounds like a load of crap then Fred, I'd steer clear mate.
I've sold NUMEROUS cars in my time and I always find it best to point at the car and say 'There it is', then they go over it with a fine tooth combe, then out for a test drive which I hardly say anything so they can listen to the car and not me prattle on, then I'll show them the history when we get back.
I think it says alot about my advertising skills that nobody has EVER viewed one of my cars and not bought it that very same day, I've been very lucky in that respect, but also don't BS about.
If a car is mint then sure, advertise it as mint, if however it's got dents and scuffs and scratches all over it, don't advertise it as mint as when someone comes to view it it's gonna make you look like a knob head,
Some people say 'Getting potential buyers to your door is the halfway mark', I agree to an extenet, but lying is stupid as once they arrive and see the car you'll be caught out.
I like to stick as much details as possible in my ads so that buyers know what the car is all about,
Keep searching though mate, you'll get one sooner or later,
EDIT: Here's my GTV V6 advert on Pistonheads, it's sold now obviously, but just goes to show that sticking in as much information as possible works, bought the car off eBay for £2000 then sold it for £2500 a month later,
(And yes I did declare those monies to the tax man,
