Flame grilled whopper
Hi, you're about to be flamed, and deservedly so.
96% of people didn't get the value they were quoted online. So your aquaintance is saying that 96 out of every 100 people, knowing their valuation may be lowered if they give false information, lied about the state of their car? Really? Is that "the main problem?"
And how is this the "lazy" people? The process is :
1. You go online and fill in several pages of information about your car, then
2. drive to the nearest "webuyanycar" garage, where the car is inspected and they give you a price.
Any other way of selling your car would involve either step 1 (eg. Autotrader) or step 2 (eg take it to your local car dealer), but not both. Not really sure how that saves you time...
It seems that, up until now, people have slagged them off a lot LESS than they deserve.
I notice you were careful not to describe this person as a friend. As the old saying goes :
"the character of a man can be determined by the quality of the friends he keeps."
