I found a decent '80s lot on Facebook yesterday. The seller only had the 6542 Seaport, 6395 Raceway, & 6394 Metro Park listed for $290. I talked her down to $225. Then she mentions that she has more not listed. She sends me some pictures and says $350 for everything. I counter with $300 and she accepted. The Slave 1 pictured wasn't included. I just didn't feel like moving it before taking pictures.
Other than some dust, everything is in excellent condition and appears to be mostly complete. The sets with boxes are all still assembled inside their box. Inside the two storage containers are parts for what appears to be some classic space and town buildings. This should keep me busy for the rest of the winter.
