What the data shows
This 2002 SL500 benefits from low miles and a robust engine, but the complex ABC suspension and SBC brakes could lead to costly repairs. Budget about $7,600 for potential hydraulic and electronic issues. The asking price is well above market, so negotiate heavily or verify extensive recent service.

Detailed findings, 10 items
Click any card for the full breakdown, repair cost, and what to check. Items already handled by the owner show as checked.
Reflects the open findings; items the owner handled are excluded.
Confirm these before you buy. If you or a mechanic can verify them, that clears the car instead of ruling it out.
ABC Suspension (Active Body Control)
The R230 SL's Active Body Control (ABC) system is known for leaks, pump failure, and accumulator sphere wear. At 54k miles, it may be okay but worth inspecting carefully.
SBC Brake Pump
Sensotronic Brake Control (SBC) pump is a known problem on early R230 models. The pump can fail or reach its finite cycle limit, triggering a service message, reducing brake assist. Mercedes had an extended warranty up to 10 years/120k miles, but it's expired.
Costly repairs, but not urgent to verify before you buy. Price them out and use them to negotiate.
Engine Mounts
Engine mounts commonly collapse with age, causing vibrations and driveline movement.
Convertible Top Hydraulic Cylinders
Hydraulic cylinders for the roof mechanism are prone to leaks over time, causing slow or incomplete operation.
Minor wear typical for the car’s age. Not worth negotiating over, but good to track as an owner.
Valve Cover Gaskets
Oil leaks from valve cover gaskets are common as the engine ages. Not urgent but should be monitored.
Crankshaft Position Sensor
A known failure point on the M113 engine, causing stalling or no-start.
Fuel Pump and Filter
At 54k miles and 22 years old, the fuel pump and filter may be original and due for replacement.
Cooling System (Radiator, Hoses)
Plastic radiator tanks and hoses can become brittle with age, leading to leaks or sudden failure.
Instrument Cluster Stepper Motor (Stuck Tach)
The tachometer needle stuck at maximum indicates a failed stepper motor, a common issue on these clusters.
Transmission Conductor Plate
The 722.6 transmission uses a conductor plate that can cause limp mode or erratic shifting. At 54k miles, it's unlikely but worth asking about any shifting issues.
Every finding still open carries a question worth asking. Copy them as one message, already ordered by severity. Anything you have marked above drops off on its own.

Caution items with repair-cost context.
Each range is what that one item costs if it turns out to be present. Not every item will apply to this car, so they do not add up to a bill. Verify with a mechanic.
Asking is $28,500 against a typical $13,500 for this car and mileage. The work is the difference, not the sticker.
Negotiate your offer
At asking, this is about 111% above the market estimate (about $15,000). The documented repairs below are the kind of evidence buyers cite to start lower.
- Documented critical/major repairs of $5,000–$10,200 you can point to.
- Strongest items to raise first: ABC Suspension (Active Body Control), SBC Brake Pump.
Pricing is in beta. The market estimate comes from research models and can be off by thousands on the same car, so check recent local listings before you rely on it. This is information to help you research, not a professional inspection, an appraisal, or financial advice.

In-person inspection
10 things to check before you buy
2 major and 6 caution findings, turned into a walkthrough for the driveway. Answers save as you go.
Before you leave: Ask the seller not to start or move the car before you arrive. A sales-ready car has usually been warmed up, and a warm engine hides the startup smoke, rattles and rough idle that the first section is built around.
Everything on this list is what you can see standing next to the car. A shop on a lift sees the rest, and a written pre-purchase inspection listing parts and labor is what a seller has to answer to. Budget roughly $100 to $150 at an ASE-certified shop.
