Well the list you mentioned, Fielder and Probox is the best cars in this. A GLI is also a good option.
Both are tough vehicles with parts availability in market.
You will find a good Probox in this price range but for a good maintained fielder you have to add some $$.
Still asking what is your priorities??
Fuel efficient ?
Comfort?
Manual auto??
Car with trunk?
If you are good with a small car, iwill suggest you 660cc jdm.
Spacious and fuel efficient.
You can also think for Swift.
