Resale on your swift is very good. My wife will rade hers for another one sometime this year (it's all round a better car than ours) - 4wheel disks, 6 arbags, better fuel economy, etc. Pleanty of places to do modifications too.
But yours has only 38k on it, you may as well keep it, until it starts having problems (which ours hasn't). Many run 200-300K kms with no or minor issues.
