id really like to hear your offer first.
it is a 2012 vanguard and I do know they had problems til the 2013 board was put in.
I don't expect to pay the price you have there as I don't think they keep their value like a luxe can.
I believe it is a buyers market at the moment so realistically I expect about 700.00 for luxe taking a 150.00 drop from when a bought it on only a few months ago but I don't think a demon can be worth more than 250.00.
