The first-generation Skoda 105, 120 sedan is a compact family car built around simple mechanicals and rear-wheel drive. It was meant for everyday running rather than luxury, with a practical body and straightforward controls.
A typical Skoda 105, 120 engine is a small petrol unit paired with a manual transmission, as in the 1.1 MT and 1.2 MT sedan examples. Both use rear-wheel drive, so the powertrain stays simple to live with. You get modest everyday pace rather than strong acceleration.
