How is the market where you live?
Im in upstate NY, around here a motorcycle over several years old, in good riding condition, seems to settle out around $3000.
it does not matter if its a 650 or 1100 or 1600, once a Vstar bike gets to a certain age, its more a matter of the mileage on the odo, how well its been maintained, new tires...
I got my VS650 2005 in 2013 from the original owner with 9k on it, for $3300
Got my 2000 Royal Star in 2018, with 22k, from the 2nd owner for $2500. It needed a new front tire, oil change, air filter, plugs... so I put maybe $3000 into it total cost.
Here its a buyers market - a lot of people bought new cruiser bikes and then never rode them much. 5 to 8 years later they are a great deal for the buyer.
Check the date code on your tires, with only 8k miles its possible you have the original tires. Once they get more than 5 years old they will skid really easy (dried out). Ok to practice on and putter around town, but when she is ready to get on the highway you will want newer tires. The date code is molded in the sidewall, after the letters DOT. I aways have to google it to read the 4 digit code... I think its week of the year, and 2 digit year (assuming after 2000) so 1208 would be the last week of March (12th week) in 2008...
