Have someone who is objective and dispassionate read what you've written.
Then have them give you honest feedback.
When I sell a vehicle, I sell it. No build up, no 5 page long descriptions, no theatrical descriptions of "The Good, The Bad, The Ugly". No soliloquies about how painful it is to sell it. After all, business decisions are cold and black and white.
I sell with just a plain description with an "As-Is", whether I loved the vehicle or not. No grandstanding, no requirements for proof of worthiness, no theatrics.
You have the right to sell, but not to discriminate. You might want to run your long sales pitch through a lawyer, especially re.: your requirements.
In any event, my associates and I feel your advert is grandstanding.
Whatever. I don't know you [and you might just be the next best guy next to Clark Kent], but in all appearances it is... out of the ordinary behavior.
MHO...
