I’m not in the market for new modulars, but just to clarify – $1050 for all three, already assembled? with boxes and instructions in good condition?
IMHO average price might seem fair to a seller but is not a selling point for a buyer unless you are only comparing sales in the US because costs in other countries are often much higher. On the other hand, having no shipping cost is definitely a bonus.
This person seems like a good candidate for the LUG.
