As far as I know most used vehicles are sold "As is" with no warranty.

It's not always possible to have a mechanic inspect a used vehicle before purchase but it is recommended.

Each state has their own vehicle laws when it comes to used vehicles.

As Hoppy stated, most vehicles are sold "As Is."

I was in the car business in Nevada for many years (new and used) and unless specifically stated on the vehicle's window as to whether or not a warranty is offered by the dealer, you are on your own if it is checked "As Is."

Always have a mechanic check a used vehicle unless it is a "Certified Vehicle" from a reputable dealer.

I'm sorry to hear that you are having problems with your (new to you) vehicle, OP.

I wish you luck.

While researching I was reading where failing to disclose any information that would negatively impact a buyers decision (especially when it won't pass state inspection) was considered fraud.

 

Is that incorrect?

I know in my state there is a fairly good Consumer Protection division within the attorney general's office. The advantage is that it's free.  The cost of running a legal office requires lawyers to charge a fairly high hourly rate to cover the costs of insurance, office staff and rent.  To file suit on a $6000 claim is hard to justify. These things are rarely clear or easy.  You're not going to be happy paying anything, since anything less than full restitution is a loss to you.  Unless the lawyer needs to up his pro bono hours, he's not going to be happy receiving nothing for what could be a day's work.  There are often pro bono clinics for consumers at law schools.  These kids act under a supervising attorney, and they have all the time in the world to harass their opponents.  So you could call your local law schools and ask if they have such a program.

I would start with "free" first.  It does sound like you got ripped.  You would most likely need a mechanic who would document the condition of the vehicle, and be able to testify how the seller's misconduct deprived you of the benefit of the bargain, i.e. how much it is truly worth compared to what it would have been worth with a normal amount of wear, tear and rust.

A lot of the rules do NOT apply to single individuals.
They apply top dealers.

The majority of used auto sales are "buyer beware". However some states have very good consumer protection laws that may give you some recourse.

Another posted covered the law clinics at most law schools, which may be worth checking out. Hiring an attorney in this case would likely cost you more than you would recover.

We don't have State Inspection in Nevada.

All we have is a Smog Test for vehicles over a certain year and used car dealers have to guarantee a Smog Certificate for the vehicle at the time of sale.  

If a dealer sells a used vehicle "AS IS" that is just what it is AS IS (as long as it will pass Smog).

That's just the way it is with used vehicles, Bro.

At least in my state.  

You might want to look into the title issue.  You may be able to cancel the sale and be entitled to your money back if they can't deliver title within a certain time period.  I bought a Mustang from a dealer once.  Transmission noise developed within a couple days and the transmission completely blew up within about 3 days.  Turned out they didn't have title to the car at the time of the sale and I was able to return it to them.  That was VA, and you're in TX, but it might be worth looking into if they still haven't delivered the title to you.
