Lemon law is very specific, most people don't know what legally qualifies as a "lemon". Majority of time it doesn't apply when people think it does, doing a ton of research first before any final delivery is essential to even contemplating bringing local, state and federal law into the mix.
Know all that because I know Peter Maier. He was the one that wrote the Lemon Law and I've only had to have him help me once with a supposed 'new' car back in 95' or 96' which was an interesting coincidence.
Like any major purchase in life, do your research first digging as deep as you can helps to make a good decision vs a bad one.
