Yes, congratulations... braggart! No, just kidding. A very eclectic as well as impressive group of vehicles.
The chassis on these cars are marvelous and so, they can handle more power than the n/a engine normally produces, AND you've been exposed to the 650hp/torque of the ZL1. So, how long til ya start to "modify"?
The car is beautiful BTW and one day will be a rare bird (keep all the OE parts?). If your wife bought it, she's a rare bird too. I'd definitely leave her stock! Enjoy both!
