Desperate for help! Automotive Issue

I traded vehicles using an online forum -- well the person I made the trade with did not tell me of multiple mechanical issues with the car. There were also modifications that I was told were done, but later on found out that they weren't. Is there anything I can legally to do make him pay for the cost of the issues and the missing components that he told me were on the car? I would like to either make him pay for these issues or at least get the other vehicle returned to me. I appreciate any help with this.

Heres info on the 'contract'

It simply states that a direct trade was being made between vehicles, it does not state anything as to the running condition or anything else it states

"A direct trade with no money involved is taking place for the 2 vehicles listed below.

My name is trading a
Car Make and Model VIN #
For His name
Car Make and model VIN:#

Signatures here"

Here's a direct link to his ad for the car
1990 Eagle Talon AWD 5spd 372awhp Clean - LS1TECH
and I was just adding in the other information to let you know what he had told me of the car, which was that it was in fine running shape. Thanks for your help with this guys I do appreciate it. Also does that constitute fraud in misrepresenting the parts that were supposedly on the vehicle?

anyone?

Based on what you say here, you could file suit against him (or at least threaten to do so) in small claims court or in regular court; filing in small claims court is easier and requires no attorney...you could try to collect all of the costs and damages that you suffered due to his behavior... You may also report him to your state attorney general's office if you suspect outright fraud. World law's attorneys could also become directly involved, email them too if need be.

Thanks for the reply, that's the info I needed and yes it was outright fraud IMO. I'll be in contact with these attorneys and see if they can help me.
