This is only partly true. Dacia made a conscious decision in the design of its cars not to chase EuroNCAP safety ratings by fitting equipment which all the research shows people just switch off.
I've got a Jogger, new in 2024, which has a one star rating. It was always structurally sound, but lost many points in its test because of advanced driver aids like lane-keeping assist not being fitted. Then, from the start of April 2024 all those features which Dacia had declined to fit became compulsory on new cars in the EU anyway. So my Jogger, built in June, has them but still only the one star rating.
As well as the Jogger we have two Logans, none of them have ever let me down. With your budget you'd be looking at a brand new Duster (new generation, only just gone on sale here) which will have all the safety tech and if you get it serviced at least once a year at a Dacia/Renault dealer then the warranty will be automatically extended out to eight years. That's pretty compelling if you're concerned about reliability.
If you've got three kids, may I also suggest you look at the Jogger? Very similar to the Duster, but seven seats for when the kids have friends along, grandparents, etc. It's the perfect car for us.
