How about a Nos system for another $1500? It's nothing compared to the on-going $80K. As you see that there're a lot of Dodge Magnum Charger, Chrysler 300, BMW 5 series, or even Mercedes out there think they're kings. Show them what Lexus is capable of.
if anything... i would not run laughing gas. I would just S/C the sucka. maybe since im going for the VIP theme to it.
