Who sets the fair deal verses great deal for carGurus?
How is my car a 2006 Infiniti with 104,700 miles for $7,999 considered a fair
deal, when there's another (along with several other same models) Inf 2006
with 160K miles for $7,995 considered the same fair deal?
It's all based on the ad prices of other vehicles on this site. Nothing more. But remember you are selling privately, and you can't compare your price with vehicles from dealers.
If you bother to look at the rating it tells you Exactly what the price comparison means.
