so one thing i keep seeing in various forums and even in reviews, is that TCO (cost of ownership) for the diesel may not provide a break even point because of the price of diesel... which has me somewhat confused as locally diesel is selling for .05 a gallon more than unleaded. so is that an anomaly? i know there was a period diesel was more but that seems to have not been true for a while now. so almost 50% better MPG compared to just about any gas V6/V8 for .05/gallon more? not seeing how this is not a good value, even for $2800-$4K (hemi/penstar), over 5-7 years + potential higher resale, what is it that has people saying there's no 'payback' for going with the ED?
