I have a friend who does auctions for a living. He buys salvaged hondas, fixes them, and sells them.
There is money to be made if you have the time, and know which ones are good to buy.
I bought a salvaged 99 Civic Si for only $6k (theft recovery), dropped $2k into it to restore it, so $8k investment total. I drove it for 2 years and then resold it for $13500.
Some people actually PAY to own a car. I'd rather GET PAID to own a car! There's no better deal anywhere.
