The exterior curvature of the body was also drawled with a windshield that is wrapped around the fender lines. The Mercedes 300 Series was actually available in different variants like the coupe, cabriolet, and the roadster. Every one of this comes with a leather interior while the dash is in walnut trim with a touch of chrome. During 1953, the Mercedes 300 series specifically the cabriolet have used an automatic transmission and a six cylinder engine that is capable to produce about 150 hp. From 1951 to 1958, the Mercedes Benz 300 Series were sold continuously in the market. From the most classic style to the most moderns, every detail was of high standards. The materials that were used came from the latest technology with the most minimal weight and a higher degree of strength ability. With the body frame itself, the construction has maintained a high level of quality. Its front end was suspended permanently using an independent suspension with coil spring and A-arms. The Mercedes 300 Series vehicle models move fast but still keep the comfort and relaxing feel during the ride. But of course, this Mercedes 300 Series was produced only in limited number that is why it was considered as an exclusive vehicle.
