In my area any car that doesn't need any reparation or work being done on it is sold at a minimum of 900€ and speaking of Clio of that era they are more like between 1700 and 2000€ if you want one in working order.
That is the funny thing with the second hand market. 20y old cars sold 20k€ or 80k€ new are sold more or less at the same price 20 years later. Because of higher maintenance cost and parts price + higher number of stuff that can fail, the more luxury items are also the ones that are less wanted and people looking for inexpensive cars will favor the most sold small cars of that era they or an independent garage can fix easily and cheaply.
