Dude who the hell is trying to sell you a freakin 84k warranty for $1800? On my 99, the 100k Honda Care warranty was like $1200 and I didn't go for it. I think I made about $250 worth of repairs during that time that would have bee covered by the warranty.
Extended warranties on Hondas are simply not worth it. Maybe if they're 1st year, but the Accord has been in its model cycle for 4 years now.
