I'd be really careful of this one. Any time a car is marked down from $3999.00 to $1499.00 there's likely trouble. A used car like this from a private individual is one thing, when you can talk to the owner and review the history. But it's another thing to buy a car like this from a dealer who is generally trying to make money from the sale. It doesn't look like there'd be much in it for him, if anything. He's trying to unload this one and there must be a reason for it.
If you buy it you can expect to find problems in the near future that will cost money. Take it to an independent mechanic and see if it burns oil, check the compression, look at the brakes - everything. Spend a hundred bucks on that and make sure that you know what you're getting
