I think that's awesome. I remember you and I were cross shopping the same two cars at the same time. The SHO or the 13' MKZ. Funny you ended up with the SHO and me the "Z". The certificate is great, I have an 07 GT500 Red Appearance Package with a number 151 build according to my certificate. I have to be honest, I love the MKZ but always felt like I screwed up not getting the SHO instead. I'd love to trade the "Z" in for an RS. Just owning the GT500 makes me long for something a little more spirited for a daily driver.
