It sounds like this may be some additional information added to a similar question that you just asked. With the additional information that you have supplied, it sounds like you may have some rights against the dealer. Just because it was sold to you "as is" does not mean that you are necessarily out of luck. If the dealer concealed a material fact from you about the vehicle (like the engine was about to blow) or misrepresented the condition of the vehicle to you, you relied on the dealer's representations about the vehicle, your reliance was reasonable, and you were damaged (i.e. you have a major repair bill), then you likely have a claim for fraud. You may also have claims under New Jersey's consumer law statute. However, laws vary from state to state. So, as I indicated in my last answer, you really should contact a consumer law attorney in New Jersey to see if you have a case worth pursuing. Here is the link again: www.UsLemonLawyers.com.
Best of luck,
