G35? Lexus IS250? Altima Coupe?

what you guys think is a better car right now as for today. The 2006 infiniti G35 coupe, marked at around 20k, the exterior is beautiful but the interior is a little lacky. 2006 Lexus IS250, also marked around 2006. and the all new 2010 Nissan Altima Coupe, fully loaded is around 30k, but is clean inside and out. please give me some thoughts, im stuck between these three cars right now.
