Romania
With 18 appearances, and 18 finals, Romania is one of the most successful Eurovision countries, that are yet to win. That is, if you look aside the years with pre-selections before the introduction of semi-finals. The country first tried to participate in 1993, but it wasn't until 1994 they actually made it to Eurovision.
The country has been steady at the Eurovision Song Contest since 2002, although in 2016, Ovidiu Anton was disqualified a few weeks before the contest started due to TVR's depth to EBU.
In 2005 by Luminița Anghel and again in 2010 represented by Paula Seling & Ovi, Romania finished third - which to date is their best placement, but they also have Mihai's fourth place, a 7th place from 2017 and finally a 9th place from 2002, as other good top 10 results.
