I happen to know someone who is a 10+ year master mechanic for Infiniti and knows P10 G20s inside out and upside down. He was talking about writting a tutorial on all the most common problems with P10s and what to do to fix it. Compiling this data would take him a few weeks of his free time (evenings and weekends as time permits). Anyway, I suggested asking around first if there would be an interest before dedicating so much time to a project. So my question is, if he does this, would you be willing to buy the guide? How much would you be willing to pay? My guess is that he would want somewhere between $15 and $35 depending on how many he could sell. (If only 4 people wanted them, I'm not sure he'd bother to do it.....) ....so what is the interest level out there and how much would you be willing to pay?
