What can I do about a truck I bought?

[commanderx777]

I know I've made a huge mistake but I bought this truck from a guy who was selling it.When I went to look at the truck it was in OK condition,it needed some minor cosmetic repair,new window but he told me it ran fine.Rebuilt engine and when taking it for a drive it was fine.I paid him 1,400 cash.Big mistake.He gave me the title.I went to the Title place in my city and when I went to register it,the title was not clear because the truck was a rebuilt salvage.The guy did not sign the title either.He also has to fill out a salvage report and the truck has to be re inspected.I called him and he said he would fix the paperwork so I could get a clear title.He said that he could take it to a friend and get it inspected.It's a class 3 felony to forge paperwork.I told him I just want my money back,the truck is also leaking oil now and jerks badly when driven over 40 mph.He said he would take back the truck and resell it and give me the money,which I know he won't.What can I do?
The problem also is I can't sell it because I can't get the title in my name.This guy is being an @ss about it now and puts his wife on the phone to talk to me,he won't talk to me anymore but is coming today to pick up the truck and try to re sell it then give me the money if it sells.I know he is going to run off with it.He said he didn't have the 1,400 I gave him because he paid his house payment with it.He owns a business as well.I know it was stupid on my part to buy from him.I should of been smarter,I just feel sick that I lost this cash..any advice on what I can do to recover my money would be great.I've been just torn apart over all this and am a few hours away from meeting this @sshole and if he starts with his smart remarks,I'm afraid this is going to turn into a fight..
I also live in Bexar county Texas,if this helps any.
