The full service sounds like a complete overhaul. Gues list stuff like that on CL all the time Bike for sale just service xx.xx new tires xx.xx cables xx.xx it looks cheesy and gives the impression they are only after as much money as they can get.
IMHO selling a bike with a damaged front wheel is neglectful and as bad a selling a car with bad brakes.
you have a bike that you are not using and you spend 10 min posting it on craigslist (CL) and maybe get a quick $100-150 (listing as is for parts only) for your pocket. you can schlepp it to the shop spend 200-250 to get it service and the spend 30 min listing it on CL listing each new part and the price and wait maybe until June to get maybe $340-400 for it. About the same 100 bucks either way
