Found a leak in front of rear right hand side tyre

There is no "oil" arround the area of the front wheels. The possibilities are a leakage of brake fluid (either from a brake caliper or brake flexible hose) your car is rear wheel drive so its not a case of a CV boot leaking grease , power steering fluid could be leaking from the steering rack boot or being sprayed out under pressure if a power steering hose is going bad.

Same problem 1996 sl 320 . Turned out to be a leak on a hidrolic cilender opperating soft top

mine turned out to be a hydraulic leak
