The issue here is the fact that there is us ie "car people" and them "your standard issue eejit" in regard to public sites like donedeal. We want clear honest information, they want to sell the car. Are not aware of, do not care or are hoping issues and little white lies go unnoticed.

This can work to the enthusiasts benefit some times but more often against as that 316i really is an M3 no matter what you say to them and the "I" refers to the interplanetary warp drive installed by their mate last week....

Personally, I'm used to buying things in general that are clearly labelled and priced as society dictates via advertising so a lot of the frustration with car sales ads comes from unclear information and pricing.

I'd want :

Honesty (lol)
Spec
Work done
Work needing to be done
Price
No bullshit.

When they are missing it grinds my gears....
