The Škoda 105, Škoda 120 and Škoda 125 are three variations of a rear-engined, rear-wheel drive small family car that was produced by Czechoslovakian car manufacturer AZNP in Mladá Boleslav, Czechoslovakia between 1976 and 1990. Engine sizes were 1.05 and 1.2 liters respectively.

The range was face lifted in 1984 with a revised design and engine improvements, together with the introduction of a new 1.3 liter version known as the Škoda 130. The related models followed in 1987 with the Škoda 130/135/136.

All 105/120/125 and 130 models known by their Škoda internal reference as Type 742,^[2] and the later 135 and 136 models as Type 746.^[3] In the UK, the 105/120 models were known as the Super Estelle until 1984, when the face-lifted models were called Estelle Two.

In the early 1970s, Škoda had originally intended to produce their successor to the S100/110 as a front-engined front-wheel drive model. However, because of the lack of funding (Škoda had even applied for license in Moscow to produce their new car with a front-engine and front-wheel drive), Škoda was refused a licence and was forced to update the earlier S100/110 saloon models. The main reason Škoda was not granted a licence to produce their new car was because it could have been more modern than cars from the Soviet Union.^{[citation needed]} At that time, most cars from the Soviet Union had either a front engine driving the rear wheels or a rear engine driving the rear wheels. There was even a front-engined front-wheel drive Škoda 105/120 prototype, which looked almost identical to the rear-engined one.

The Škoda 105/120 went into production in August 1976. Despite being basically the same as the previous S100/110 under the skin, the new cars featured a lot of improvements, such as a front-mounted radiator with a thermostatic fan. The heating unit was now inside the dashboard, and the fuel tank was now underneath the rear seat. All models had much the same mechanical specification as the previous models, with a 4-speed gearbox, independent suspension at the front, worm-and-drive steering, and swing-axle rear suspension. An interesting feature found on the 105/120 was the side-hinged bonnet, which opened up like the top of a concert piano.

The Škoda 105/120 was initially available in three model forms with a choice of two engines: the 105 S and 105 L were powered by the 1046cc (44 bhp (33 kW; 45 PS)) engine, while the 120 L was powered by the 1174cc (49 bhp (37 kW; 50 PS)) engine. The 120 LS and 120 GLS models, which had the more powerful 1174cc (54 bhp (40 kW; 55 PS)) engine and higher levels of equipment, joined the line-up in 1977 and 1978 respectively.

Until 1979, both 105 and 120 were equipped with 14" wheels, with 155 SR 14 tyres, just like its predecessors, S100 and 1000 MB, but since 1979, due to an increased gauge, both models were given 13" wheels with 165 SR 13 tyres for 105 S/L/GL and 120L/LS versions, and GLS versions were equipped with 175/70 R13. This update was made in order to improve road handling, stability, performances and fuel consumption.

The cars were initially criticised for unpredictable handling "at the limit" but it is unlikely that most motorists would notice anything untoward under normal conditions. The cars continued to win their class with monotonous regularity on international rallies, and were increasingly popular with budget-conscious motorists across Europe. The location of the radiator at the front of the car had the advantage of cooling the engine much more efficiently on the motorway. However, because it was much more complex than in the earlier models, the cooling system was very prone to airlocks, which often led to overheating and even head gasket failure.

The existing 105/120 lineup was joined with the 120 LS in 1977. It had a more powerful 54bhp version of the 1174cc engine from the 120 L as well as a higher equipment level. April 1978 saw the arrival of the top-spec 120 GLS as well as the 120 standard model.

In March 1981, the 105 GL was added to the lineup. It was mechanically identical to the existing 105 S and 105 L models only it featured the equipment specification of the 120 GLS model. Both the 105 GL and the 120 GLS were given black bumpers and horizontal taillights.

In November 1981, the range was supplemented by an attractive Škoda Garde coupé, which was equipped with the 1174 cc, 54 bhp (40 kW; 55 PS) engine from the 120 LS and 120 GLS Saloon models. This had much improved semi-trailing arm rear suspension, and paved the way for the 130-136 models of the late 1980s. The later coupé Škoda Rapid was a facelifted version of Škoda Garde.

In November 1982, the 105 SP and 120 LE were added to the range. The 105 SP essentially a commercial version of the 105 S, having no rear seats and no glass just solid metal in the rear doors; it was only available in Czechoslovakia, sometimes used for postal delivery. The 120 LE was identical to the 120 L but with a modified top gear ratio to improve fuel economy (hence 'E' for Economic).

The Škoda 130 models followed in 1984 and introduced many improvements into the existing 105/120 range. The very first Škoda 130 models were introduced in August 1984, shortly after the earlier Škoda 105/120 models were given a mild revamp. Developed from the earlier Škoda 105/120 models (some of which continued [alongside the Škoda 130 models] in production, like the 105S, 105L, 120L, 120GL, 120LS, 120LX and 120GLS), the 130 series used a new 1289 cc engine (which produced 58 bhp (43 kW; 59 PS), and which was just an enlarged version of the 1174 cc engine used in the 120 series); this 1289 cc engine also saw use in the car's successor, the Škoda Favorit.

In addition, the rear suspension was now redesigned to a semi-trailing arm layout, and the track of the car was widened to 55 inches (1395 mm). 5 speed gearboxes and "four pot" front brake disc calipers were other updates. The new models countered the earlier criticism that had been made in some quarters of tail-happy handling, with the prominent UK motoring magazine "Autocar and Motor" remarking in 1988 that the new 136 Rapid model "handles like a Porsche 911".

In 1987, with the introduction of the new Škoda Favorit, the Škoda 105/120 series was trimmed to just the 105 L, 105 SP, 120 L and 120 GL. The 125 L (which was identical to the 120 L but with a 5-speed gearbox) was added in October 1988 and was the final model to evolve from the 105/120 series.

From 1989 onward, production of the 105/120 series was gradually wound down as production of the Škoda Favorit progressed. Production of the 105 SP had ended in July 1988, followed by the 105 L and 120 GL in January and November 1989. The 120 L and 125 L (the last remaining models of the 120/125 series) were finally discontinued in January 1990. After a production run of fourteen years, which included a total of 1,961,295 cars (counting just the Škoda 105/120/125 series cars alone), production of the 120 L and 125 L (the last remaining models of the Škoda 120/125 series) ended in January 1990.

On October 5, 2004, a survey conducted by AUTOSALON revealed that among the 3,706,012 cars registered in the Czech Republic, 1,780,124 were Škodas. At 305,726 cars, the Škoda 120 was the largest model represented, while there were 216,857 Škoda 105 cars, which made that model the fourth most common Škoda car.
