Whether or not you have saved enough should be a function of living expenses, not wages.
If you have $5k and can live on $600/month, that's great. If you need $1k/month in expenses, then it's not great at all.
As soon as possible, you need to have enough saved to cover an unexpected, large expense (car/home repair, medical emergency, moving to a new place, etc.) and at least 6 months of living expenses. I personally have at least 12 months of living expenses at any given time.
start by adding option to "feature" the car in the sidebar or somewhere. just make small changes that add value ( speed up the buying-selling process )
