I had talked to an Attorney at this firm years ago. The Attorney had formerly worked for a Big 3 auto manufacturer handling Lemon Law claims so he knows what the manufacturers weak points are. He did tell me they recover everything including registration fees, even if you added things like a trailer hitch. They also get Attorney's fees from the manufacturer.

The website says Florida but if they don't do other states maybe they will give you a referral. The Attorney I spoke with was pretty impressive.
