I paid 225 for the next size smaller a two burner Weber . I love it , I also have a much larger charcoal grill for larger stuff . I would offer 300 . It's a very good price at 300.That looks like a stock photo , his grill might look much worse , if it does 250 . If he has an offer for 400 , why is his listed for 300 . You need to go and look at it . Open those doors and look up top left . That's the grease trap . Is it clean or rusted out . The flavor bars(little metal v shaped angled pieces that fit over the burners) , pull one up and look under it , that's the burner . Is it ok or rusted out . Was it always stored inside or out ?
