I can't tell you much about the 280 but I bought my current G from Norm. I made the mistake of buying sight unseen. Everybodys vision of perfect is different. Norm was very straightforward and addressed any issues I had with the truck. I think he is fair and does a good job with the G. I know of a couple other satisfied buyers as well. Besides he is about the only one in the US with inventory. I wouldn't hesitate to reccomend buying from Norm.
