I lived in Romania for a few years and can confirm that all the dacias are built of renault designed bits.
I had a few of the dacia logans (04/07) and they were all the bits out of a late 90's clio.
But on the subject of a baby Dacia, you may be quick to dismiss, but it's alot more likely than you'd think.
While dacia is new to the uk, they have been a budget brand in france for over a decade and much like VW have the skoda/Seat/vw/audi development chain. Dacia is a renault development brand that they are looking to build in developing markets, where tech demands are lower and price is the main sales decider.
If you travel to the middle east, southern europe and africa you'll come across loads of Dacias bumping about!
While I agree it may not be sold into the uk, unless imports start arriving on the grey market, the development of the current fortwo/twingo floorplan into a baby Dacia is pretty much inevitable, its a simple mattter of bottom line, the floorplan is there, they have to make parts for the twingo for a while even after they update it, so a Dacia version is the natural next step for the Renault management.
By the way
The dacia logans I had were a genuine giggle, it was basically a clio and as anyone who has had a clio will knows they handle really well. After a set of springs and new wheels they are an absolute riot! I had the 1.5 dci and the 1.4 petrol both had absolutely no creature comforts! Manual everything, no radio as standard, you were buying the bear minimum of a car. But that made em bullet proof and anyone can fix em.
I've often thought they would make a fantastic sleeper car, as I saw what the young lads of romania had managed to do to theres,
hmmmm might add dacia logan to my flea bay searches!
