I guess in my opinion, you have to ask yourself if you think it's safe for your family, and yourself to be in. I sell cars part time for my father, so this is what I have to say about your trade in. If it is just a base version, your car is worth about $3000 if it is in average condition, no dents, somewhat clean, etc but the market in these has been really bad, so don't be offended if the dealer only offers you $2000. .Without actually seeing the car, it's hard to tell. The Suburu that your looking at, if it says moderate damage probably means that they ran into some things, so small dents, keyed it, so the paint and body work probably have been done over quite a bit, but then again it should be a bit cheaper than what one in mint condition would be, if you can live with that. If you do consider buying this car, I would take it to your favorite, most trusted auto mechanic, and have them put it up on a hoist, and make sure that there isn't frame damage. I know that the Carfax report said that there was none, but better safe than sorry, and they can take a look at some other things that might be wrong with it, oil leaks, exhaust problems, etc. If you PM me the info on the Suburu, I could probably get a better idea on what you should pay. If you sell your car on your own, you should be able to get around $4500-$5500, so that might be an idea, and then you should get a better deal, by not having a trade in.
