To help make backing safer, the Mustang Premium’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The SLC doesn’t offer a cross-path warning system.

Both the Mustang and the SLC have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems, rear parking sensors and driver alert monitors.

Ford’s powertrain warranty covers the Mustang 1 year and 10,000 miles longer than Mercedes covers the SLC. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 5 years or 60,000 miles. Coverage on the SLC ends after only 4 years or 50,000 miles.

There are almost 8 times as many Ford dealers as there are Mercedes dealers, which makes it much easier should you ever need service under the Mustang’s warranty.

The Mustang has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The SLC doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the car’s engine.

J.D. Power and Associates rated the Mustang first among midsize sporty cars in their 2018 Initial Quality Study. The SLC isn’t in the top three in its category.

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Ford vehicles are better in initial quality than Mercedes vehicles. J.D. Power ranks Ford fifth in initial quality, above the industry average. With 11 more problems per 100 vehicles, Mercedes is ranked 14th.

To lower fuel costs and make buying fuel easier, the Ford Mustang uses regular unleaded gasoline (premium recommended for maximum performance). The SLC requires premium, which can cost 20 to 55 cents more per gallon.

The Mustang has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The SLC doesn’t offer a cap-less fueling system.

The Mustang offers a manual transmission for better acceleration, control and fuel economy. The SLC doesn’t offer a manual transmission.

A ten-speed automatic is available on the Ford Mustang, for better acceleration and lower engine speed on the highway. Only a nine-speed automatic is available for the SLC.

The Mustang Manual’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The SLC doesn’t offer launch control.

The Mustang GT’s optional tires provide better handling because they have a lower 30 series profile (height to width ratio) that provides a stiffer sidewall than the SLC’s optional 40 series front and 35 series rear tires.

For better ride, handling and brake cooling the Mustang Premium offers optional 20-inch wheels. The SLC’s largest wheels are only 18-inches.

The Mustang’s instruments include an oil pressure gauge and a temperature gauge – which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The SLC does not have an oil pressure gauge.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Mustang has standard extendable sun visors. The SLC doesn’t offer extendable visors.

Standard air-conditioned seats in the Mustang Premium keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The SLC doesn’t offer air-conditioned seats.
