Mercedes-benz Sl450 problems
The Mercedes-Benz R107 and C107 are sports cars which were produced by Mercedes-Benz from 1971 until 1989, being the second longest single series ever produced by the automaker after the G-Class. They were sold under the SL (R107) and SLC (C107) model names in a variety of names indicating the displacement of the engines.
The R107/SL was a two-seat convertible with a detachable roof. It replaced the W113 SL-Class in 1971 and was replaced by the R129 SL-Class in 1989.
The predecessor W113 was notably successful in North America, with 19,440 units (40%) of 48,912 total units sold in the US. The R107 and C107 were even more focused on the American market, with specialized engines, bumper designs, headlights, and emissions management designs. The R107 and C107 sold 204,373 units in the US (68%) of 300,175 total units sold (excluding grey market sales into the US).
During its production run, the SL was the only roadster offered by Mercedes-Benz. The C107/SLC was a four-seat car with a fixed roof and an optional sliding steel sunroof. It replaced the W111 Coupé in 1971 and was in turn replaced by the C126 S-class coupé in 1981.

Common Problems with Mercedes-Benz SL450 Cars
Mercedes-Benz SL450 cars are known for their luxury and performance, but they can also have some common problems that affect their reliability and cost of ownership.
- Interior Trim and Seats: The interior trim can split, seats can collapse, and the dash can crack. These issues can affect the car's appearance and comfort, but they can also be expensive to repair.
- Mechanical Issues: The V8 engine in the Mercedes-Benz SL450 is generally strong, but it can use plenty of petrol. Mechanical issues can arise, such as timing-chain replacement, which can cost between $500 and $1000 in labor alone.
- Emissions Equipment: Meeting federal standards required new emissions equipment in the 1975 450SL, which can cause overheating and issues with the valves, controls, and other equipment in the climate-control system. These issues can be complex and expensive to repair.
- Suspension and Steering: Suspension and steering issues can arise due to wear and tear or modifications. Check for worn shock absorbers, bushings, and excessive play in the control arms and ball joints. The steering box can also wear out, causing issues with the accuracy of the steering.
- Brakes: The W107 is a heavy car, but it brakes perfectly with its brake discs all-round. Check for brake pad thickness and any screeching, which might indicate that they need replacement. A spongy feeling on the brake pedal means there's air in the brake lines, so it needs bleeding and a leak check.
In summary, Mercedes-Benz SL450 cars can have several common problems that affect their reliability and cost of ownership. These issues can include rust and dampness, interior trim and seats, mechanical problems, emissions equipment, suspension and steering, and brakes. Regular maintenance and inspections can help prevent or identify these issues early on, but they can still be expensive to repair.
