Beware of dealing with Mark Nixon

I have tried all kind of ways to get my money from Mark Nixon on a deal that we had over 4 years now.
I feel that i have given him way more than enough time to get this setteled but still nothing, so here is the story on how he owes me $1,300.00.

I had a early 90's dodge turbo diesel truck that I had $2000.00 in to and mark said he wanted it and he had a rusty 87 V6, stick dakota that i wanted to use under a streetrod project so Mark came out with the dakota on his trailer and picked up the diesel truck and we agreed on taking $700. off my truck for his Dakota and he said can you trust me for the $1,300.00 ballance and as I thought he was a friend I let him take the truck and title, well the calls from him stopped and he stopped answering my emails to him after about 6 months.
He worked some deals involving the diesel truck with some other guy that went bad for him( thats not my problem) but I am the one getting screwed out the money for his bad deals
I have tried to get him to send me just a few $$$$ at a time when he can, still nothing. below is the last email I got from him about a year ago

Ron,
Let me see what I can do on this.
I know it's been forever on this deal and there's no good excuse for brushing it off as I have been.
Would like to get this taken care of in a manner that satisfies you, yet keeps things moving here.

Mark.

I still haven't got any of the money he owes me.

so "beware" of dealing with him, I thought we were friends and never thought he would stick it to me like this. Ron....
