Over on the X3M forum I started a Qtr Mile thread to get a feel for what the X3M might bring to the table with either 460 HP or 490 HP rated engines. But to view it alone doesn't provide much perspective, so I've worked on compiling many of the 'performance SAVs' most often referenced. Appreciation to Gudus and kozzi for mentioning others to be included. I've sorted based on different variables which highlights certain models over others. If you see errors, please share the data and your source. Thanks.
