I too have seen the Muskrat up close and personal several times, even test drove them a few times. The first one I test drove was a V-6 because my wife really liked them and she wanted to see what it was like. So we test drove it. I will admit, I thought the interior was fairly well put together. In terms of "drivability" however, I thought the V-6 was under powered and it handled very sloppy.
When i drove the GT version, I honestly felt like it drove like the V-6 should have, but severely lacked the power I expected out of a V-8. I just kinda felt cheated, like I just wanted getting my money's worth power wise... Maybe it was just me.
