Howdy neighbor, I'm over here in Winter Haven.
Yeah that looks like a pretty big bike. Dont know much about Lotus but what little i've heard wasnt bad. I believe they were made in Japan, but that doesnt mean its a bad bike. I do know that if it has Shimano 600, then its probably a good bike, because they dont put Shimano 600 on junk.
Go check it out and find out what frame material it has. If it has Tange #1 or #2 cro-moly tubing then thats some premium stuff the way I hear it. Be sure and check for any cracks or other frame anomolies around the welds and frame lugs.
It could be a pretty good bike, and the evidence of Shimano 600 stuff is a good indicator.
