Well if it's an Outback wagon with the H6 engine and an automatic transmission your payments are equal to the average price for one. If it's anything else, that price is high. Wait, with your trade in and a down payment? If the payments are that high after a trade in and a down payment, they're asking too much for the Outback depending on what you're trading in and the amount of the down payment.
A 6 cylinder Outback of that vintage is worth about $13,000 give or take a bit depending on mileage and condition.
If you're paying that much and you have to give them a down payment and a trade in, it sounds like you're either getting gouged or you're paying a very high interest rate.
You can buy or lease a basic Subaru Legacy brand new for less than the monthly payment you quoted above. Having said all that, Subaru is the only car company that isn't posting record losses recently, their sales are up for the last quarter at least.
