Here's an in depth review of the sentra. In the end they hint at an SE-R and Nismo coming in these months. If that's the case like I expected? This is why I feel comparing the SR to a GTi is premature. Though I don't think the sentra will ever be a GTi killer this generation. It gives Nissan loyalists a more entertaining option to purchase.
