awesome! I'm glad to hear that you liked the Aurora.. I was hoping you would! I don't think you're going to regret the purchase! You're right about the Northstar variation engines.. they're nice! I think I'm being teased though.. at a car lot right by where I live there is a silver 4.0 in the dealership lot.. I'm tempted to pick it up although my 3.5 has more options than the 4.0 at the dealer.. eh. I can't let temptations get the best of me.
