Today there are around 33 million registered cars in the UK but which manufacturers have stood the test of time? A brand new study by confused.com reveals the manufacturers people still love today with Mercedes-Benz taking the top spot. Using data from The Parking and taking over 1 600 cars manufactured during 1930 1940 1950 and 1960 Confused.com unveiled the brands and cars that have stood the test of time and are still being purchased frequently by motorists around the world in 2021. The Mercedes automobile was first founded in 1926 the name a combination of Mercedes Jellinek and Karl Benz. One of the highest performing large luxury brands on the road today winning the votes of Brits over rivals Audi Jaguar and Porsche. Some of the world s oldest manufacturers also made the ranking Ford being one of the eldest first built in 190 selling upwards of 5 million cars per year and has recently turned its iconic Mustang into an electric vehicle for the modern era. Ford still boasts 562 cars manufactured from 1930 1940 1950 and 1960 for sale on used car sites making up almost a third of the cars from those years currently sold on The Parking. However there are concerns about more used cars on the roads. Sales of second-hand cars have soared by 6.6% due to a shortage of new vehicles and Confused.com revealed that these second-hand cars on the roads will emit 9.8% more CO2 emissions than newer ones. Alex Kindred car insurance expert from Confused.com explains why motor brand loyalty or holding onto a car for too long could be hurting the planet and our pocket. Climate concerns are a top reason to consider reducing the length of time you keep hold of the same car. As emission-free electric vehicles become more popular and affordable and as drivers become more conscious of their carbon footprint we will see more motorists making the switch from petrol pump to the electric plug. As cars age their emissions grow considerably which could also lead you to higher prices for things like Vehicle Tax fees for entering Ultra Low Emission Zones (ULEZ) and even charges on your MOT - to ensure your car continues to meet the minimum standards. Many newer cars qualify for free Vehicle Tax based on their lower emissions yet for gas-guzzling cars the price per year can reach up to £ 2 245 after the first year of ownership.
