Do you have the facilities, tools, free time, spare money to part out the car and buy a replacement? If not, you will want to sell the car whole in order to get the money as quickly as possible. If so, then sure....you will likely get more by parting out every possible part. Just realize that you really, really want to try to sell every single part and when you've finished doing that, cut up what's left and bring the steel to the scrap yard for maybe another $25 in steel. With all that said, parting a car is a TON of work and you get far less than you expect and less than what people on the interwebs will tell you. Anyone telling you the thousands you will make.....you need to ask them what they've parted out and ask to see their spreadsheets of costs and income from a partout. I've done a dozen cars and the first few, I would have sworn that I made $3k. Then I kept a spreadsheet. The shipping companies made more than I did and my total was closer to $300 than $3000 (90's Hondas/Acuras).
I find that to sell every single part in a car takes roughly 3 years.
Listen to him!
I parted out a 04 sti quite a while back and I still have random parts all over my house and shop. I did make money (and I even put the trans and rear dif in my 02 wrx), but it was a lot of work. If you are working by yourself and have never done it before, it's going to take a long time if you're working only in the evenings and on weekends. The one I parted had very little body damage, so I was able to sell every panel off of the car except for the bumpers and shell (which is still sitting in my yard). If the engine, complete drivetrain, and interior are in good condition, you could probably expect to have around $9000 when you're done, but if it was that bad of a wreck, I'm betting a lot of the suspension and drivetrain parts will be damaged.
If you're selling everything on here, be prepared for the vultures. You'll spend hours answering messages from people wanting pics of parts that you've already posted, conditions of parts you already listed the condition of, parts that are clearly listed on you "sold" list, and all kinds of other crazy requests. I still get an occasional request for the hood scoop or wing, and it's been 2.5 years since I started the part out thread, and they were both sold the first week. After you waste a lot of time responding, they'll by the part from somebody else for $5 less. It is extremely stressful.
