Hahaha, that hella confused me. I thought your dad bought the IS-F. I was about to laugh at the fake side vents and fake quad tailpipes.
I don't know...I've never been a big fan of Lexus. They've always been overpriced Toyota's to me. I especially don't like how Japanese manufacturers use only power steering. I can't stand power steering at all. No road feel and it feels like you're driving in a video game.
Not to rain on your parade, congrats to your dad on the purchase!
