Nice feedback, Ritchie. I had a chance to test drive the 2013 IPS S a couple months back and I'll be honest--Nothing was significant enough for me to want it over my 2010 NA.
While there was plenty of little changes that do add up to an overall improved build and anyone going forward would be foolish to choose a 2010 LE over a 2013, unless of course they had an issue with the price difference. For me it would take a substantial improvement in performance or build quality for me to warrant spending another ~$80,000 on a new 2013 S (or IPS S). Plus I don't think I would get much for my current car-- perhaps $45K at best (considering the mileage). It works out to a $35K out-of-pocket for what I genuinely feel are nominal improvements at best, at least for my uses. Even with the supercharger it made very little difference on my grin factor. (I honestly couldn't tell the difference, granted my current car has a few upgrades of its own, being the Radium CAI and a straight pipe setup). I think I might on the track, but on legal roads, they both have plenty of pep to keep me smiling
