Pulled the trigger on this Mongoose Argus Comp. The guy bought it for his wife in 2018 at full retail. She rode it approximately 10 miles I paid $300. It's basically brand new. Initial impressions? This is certainly not a department store special. The frame is actually very nicely done. I like these small frames where the top tube and down tube are welded together at the head tube - super stiff/stout frame that way. But they went a step further and added substantial gusset plates in this area as well. All Shimano. 180mm hydraulic brakes. I've ridden it around the neighborhood and all seems good. Maiden voyage in the wildlife refuge will be Saturday morning! I'll have some first timer fat bike in sand impressions this weekend.
