"Vehicle needs to be viewed before purchase please. Everyone's opinion of a vehicles condition is very different This car will never be perfect it's a cat d, so please get that in your head. It's not to good to be true it's a 10 owner cat d car"
To me, that rings alarm bells about the general condition.
There can be such thing as a perfect cat D, if the repairs are done well,. and there are 10 owner cars on here that are perfect, Why should either automatically detract from the appearance?
"Everyones opinion", probably means he has people turn up and be disappointed by how something has been described in the past.
Thats how I view it, I could be totally wrong....
"please get that in your head"...
charm school trained then.
maybe "please bear that in mind" would be more friendly to a possible customer.
