I think some of the people here might be having some bit of misconception regarding the "poor student who drives up with a lexus" archetype.
Maybe the poor student has well-to-do parents? Maybe the car isn't even his, but he was just borrowing it from his parents for convenience.
I'm a "poor student" too. I scrimp and save to buy 2nd hand stuff for my hobbies. Sometimes I do drive my dad's car too, if it the convenience far outweighs the cause of driving. Showing up driving somebody else's car doesn't automatically make anyone "rich" does it? Please try to understand that students are using what little of the money they saved from their allowance and part-timing to try to fork out for some of the better lenses etc.
Of course, there's always the shameless lowballers. Age and income doesn't seem to play a part in this. I was selling my road bike and various other accessories (to fund my own camera etc), when I met this working adult in his mid 30s. 3 young kids. RSAF officer. A wife who works also. Drives a nice big MPV with TV, GPS and what-nots. Came to view my road bike and knocked $200 off this poor student's asking price after haggling for nearly 2 hours with his wife helping him. Ended up parting with my beloved bike and more accessories than I had advertised for less money.
Where is the fairness in that! Have been a "poorer student" and a even more hard seller ever since. It's rarely a win-win situation with buying/selling stuff through forums. Don't think we should be too concerned about the stereotypes either.
Offer price. View. Happy? Pay. Not happy? What to do, don't buy/sell lor. Shouldn't give in to neither "poor student" nor "rich stingy working adult". oops...
