Trying to sell a car with a blown motor for a price of a complete car is much different to trying to sell an integra in good condition for around there fetching prices. At the end of the day you got desperate people that you can crunch a lot and you got the staunch ones that won't drop a cent. Some people get lucky with bargains and some don't.
Your friend got lucky with his cause my friend did too as he bought a type R for $13,500 from $17,000 with 90,xxx km with books 4yrs ago. Considering that was a bargain back then too as they are cheaper now.
You can't be jumping down my throat mate. You know yourself sometimes you grab bargains as the seller could be desperate etc.
Anyway not here to argue, just felt bad for the bloke being told what to do trying to sell a good car. By all means slap him if he was selling a rolling shell for that much.
