A good example of a how an honest seller can be confused as to what constitutes terms such as "excellent condition" or "ready to ride" and a dishonest seller, well....

Schwinn Paramount Series 3 PDG Bike
$250
Per ad "Size: 58 cm, ideal rider 5'9"-6'2" All original components except for seat and tires. New Continental Ultra Sport tires. Pedals can be attached for no additional charge. Rear derailleur cable is slightly frayed by shifts cleanly."
First view seems ok
"Rear derailleur cable is slightly frayed by shifts cleanly"
Small dent in top tube isn't mentioned
Cables be highly rusty
Might be an ok buy for $250 but possibly other reasons for low price (internal cables might be stuck, etc).
