[335twins]

I am looking to trade my 2009 335i with 38k miles for M3. One of the dealers here has one in stock, same place where i got my 335. It is 2008, 25k miles, 6MT, Premium package, Technology package, cold weather package, moonroof, parking sensors. How much should i pay for this M3? dealer is asking 45k plus tax, title and license..From what i'm reading here, i should offer $40k otd, especially it has these nasty shiny rims which i hope they can replace for the stock ones..

Thanks
