A few questions about Dacia Sandero

A warm hello to all Dacia friends! I would like to buy a Dacia Sandero in the basic version soon. Before that I have a few questions for you. What transfer costs do I have to reckon with? Can I reduce the transfer costs if I pick up the car, wherever, personally? How much discount can I expect from the dealer if I pay immediately and cash? How are your experiences? The Sandero probably has no underbody protection. What costs do I have to calculate for this? Servo is available only from the Ambiance version. For the basic model not even optional. Is it possible to install a power steering system from a workshop afterwards? So far I drive an old polo. This is classified in the liability class 13, the Sandero in the type class 19. I had the liability calculated online and was pleased to find that the Sandero no more than the pole I have read several times about the high classification of the Sandero. But apparently the higher type class almost doesn’t matter, does it? What about repairs? Are the spare parts comparatively more expensive than other small cars. Can the repair run any ordinary workshop, or is it only possible with certain partner workshops? I am grateful for every information.
