I got a friend (who hasnt ever ridden in or driven a duramax) saying that a Duramax would own a titan and this and that about how the Duramax is a million times better than the Titan. And that the Titan is just a 350z with a truck body on it. He was talking bout how it CANT tow and what not. So then he starts bangin out about how a titan cant tow 20,000 lb's. So i was like " look neither can you stupid your truck, its only rated to tow 12,500". After that day he think that a Duramax is wayyy faster than a Titan and that a Duramax can do 140 mph. I say bs. He says a STOCK Duramax without the governor can do 140. what do you guys think? Can you help me brainstorm arguement ideas?
