Sorry mate thats crap.
If i sell you a car, and i tell you its great fantastic, you wont ever have any problems, they are perfect. What will happen the first time you have a fault, i will have to put up with you sat at my desk telling me how dissapointed you are in my withholding the truth, and the reality is you probably wont buy a car from me.
But if like i do always, treat you how i myself would like to be treated and tell you that yes the cars have faults, and there are problems but in the majority of cases these problems can be sorted out, then its possible you might think ah he is being very honest and might buy another car from me.
Salesmen have a very bad reputation, one that i hate it.
I treat everyone with respect and i would never intentionally lie to someone for a sale.
This is a carear to me not a job, thats why i have repeat customers.
