Guys, please stop responding in such manner. This is THE370Z not my350 or other Z forum. Just because OP mentioned his sister, there's no need to get all "off topic" about it. HE posted a legitimate question and he should get legitimate answer without being ridiculed (at least that's how I feel). I'm sure you guys don't want others to talk about your sister in such manner so, it's only fair NOT to talk about others . Thank you for understanding
