The Dacia Sandero is really great compared to the VW Polo, which I also have the pleasure of driving — more power, quicker acceleration, lots of space inside for five people as well as a large boot, and for me it’s a great car at a good price.

New car — but problems: water ingress in a vehicle that's only two years old, mould forming, a defective front plate and a black stain.

Hello — having tried the Sandero Stepway Extreme Auto 120.
The big downside is at the front, where large consoles on both the passenger and driver doors create a feeling that, as the kilometres go by, you have to drive with your knees squeezed together. On top of that, the small compartment between the two seats is more cumbersome than practical.
The rear seats are really spacious.

It won’t set your pulse racing on a back road, but it will make school runs, commutes and grocery hauls feel pleasantly civilized — a reliable, slightly posh companion for real life.

My wife and I have been driving a Mercedes W247 200d for seven years now, with 93,000 km on the clock. The car is very comfortable even on long trips and economical. At the last service the pads of the electric parking brake were replaced; otherwise no repairs. We love this car.
