2020 · ToyotaGR Supra 3.0
What the data shows
This 2020 Toyota GR Supra 3.0 with the B58 and 8-speed automatic is still early in its life at 26,890 miles, but the documented watch-items are the usual BMW-sourced cooling and sealing leaks that show up as these cars age. Nothing here points to a drivetrain catastrophe right now, but the platform does have a few expensive leak-prone parts once mileage climbs.
Plan on budgeting for cooling-system and gasket work over the next several years, and verify whether any coolant-loss history or warning lights have ever been stored. The asking price is somewhat above market, so the mechanical check and any repair records matter before discussing numbers.
Red flags
- BMW-Sourced Cooling and Sealing Parts
the B58 family can develop coolant and gasket leaks as it ages.
- Run-Flat Tire Sensitivity
the Supra's low-profile setup is expensive when tires or wheels get damaged.
Green flags
- Low Mileage for Age
26,890 miles means the B58 and ZF 8-speed are still early in their wear cycle.

Costly repairs, but not urgent to verify before you buy. Price them out and use them to negotiate.
Water Pump
A meaningful minority of surviving B58 cars eventually need the electric water pump and thermostat assembly, and it tends to show up as the miles stack on. When it starts to go, you may see coolant loss, overheating warnings, or a small coolant smell after driving.
Valve Cover Gasket
A common aging problem on B58 cars, especially once they get into middle age and higher mileage. The gasket can seep oil down the side of the engine and eventually create burning-oil smell or messy leaks around the turbo side of the bay.
Oil Filter Housing Gasket
A well-documented B58 leak point that shows up in a lot of owner reports as these engines age. When it starts leaking, oil can run down the front of the engine and sometimes contaminate nearby belts or hoses.
Charge Pipe
A smaller but still documented weak point on turbocharged B58 setups, especially once heat cycling and age start to add up. If it cracks or blows off, the car can go into limp mode and lose boost right away.
Minor wear typical for the car’s age. Not worth negotiating over, but good to track as an owner.
Coolant Expansion Tank
A common age-related weak point on B58 cooling systems, and it tends to get attention once cars are several years old. The plastic tank can seep or crack, which shows up as slow coolant loss rather than a dramatic failure at first.
Battery and Charging
A noticeable minority of modern Supra owners report low-voltage warnings, especially as the battery ages and the car sits. The car can throw multiple warning lights or act strange even when the root cause is just a weak battery or charging issue.
Adaptive Headlight Error
A small but recurring electronic issue on some A90 Supra cars, usually showing up as an intermittent warning rather than a hard failure. When it happens, the adaptive headlight module or connector may need cleaning, reseating, or replacement.
Coolant Pipe Joint
A small minority of B58 cars develop seepage at plastic coolant pipe joints as the system ages and heat cycles build up. It usually starts as a faint smell or damp residue rather than a puddle on the ground.

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 $55,890 against a typical $42,500 for this car and mileage. The work is the difference, not the sticker.
Negotiate your offer
At asking, this is about 32% above the market estimate (about $13,390). The documented repairs below are the kind of evidence buyers cite to start lower.
- Documented critical/major repairs of $2,450–$5,000 you can point to.
- Strongest items to raise first: Water Pump, Valve Cover Gasket.
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.
Recalls & safety
NHTSA crash-test ratings and recall data for this make, model, and year. Check recall status with your VIN before buying.
In-person inspection
8 things to check before you buy
4 major and 4 caution findings, turned into a walkthrough for the driveway. Try it on this sample.
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.
01Exterior Walk-around1
Look at the ground under the car before anything else, and separate fresh wet marks from old stains. Then walk the body in daylight: panel gaps and paint texture for past repairs, glass, lights, tire age, and the wheel arches and rockers for rust or filler. Push each corner down; it should rebound once and settle.
02Engine & Systems5
Before the first start: pull the oil dipstick and look for a milky film, check the coolant for oil or rust, squeeze the radiator hoses for hard or mushy spots, and note the battery date. Once warm: confirm the cooling fans cycle, listen for belt noise, look for fresh seepage that was not there cold, and check that the A/C blows cold.
03Test Drive1
Drive a route with stops, a hill, and some open road. Feel for shift quality, clutch or torque-converter behaviour, brakes that pull or pulse, steering play, and any noise that changes with speed or steering angle.
04Documentation1
Match the VIN across the title, dash, and door jamb. On a dealer lot, read the Buyers Guide sticker: it states whether the car carries a warranty or is sold as is, and as is means every repair after the sale is yours. Review service records and recall history, then run an OBD-II scan for stored and pending codes.
Plus 2 wear and baseline checks, added because this car’s findings are short.
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.
