What are you considering buying?

Spanner Jack will tell you the known issues, common faults, and what to check at the viewing.

Know What You're Looking At

30 years of garage knowledge, condensed.

"Underseal obscured underbody"

Spanner Jack says: Assume they're hiding rust. Garages don't underseal good metal. Walk away or get it inspected by a structural engineer.

"Failed. Passed next day."

That's a panic repair. A proper fix takes time. They've done the bare minimum to pass. Whatever failed is still weak.

"Advisory: corrosion to rear subframe"

Advisories are warnings, not failures — yet. If the same advisory appears 2+ years in a row, nothing was fixed. It's getting worse.

"Welding done at last test"

Structural corrosion was there. It may still be there under the weld. Needs an independent inspection before purchase.

Mileage drops between tests

MOT records mileage every year. If the mileage goes down, the clock's been wound back. That's fraud. Walk away.

Ford Focus / Fiesta 1.0 Ecoboost

Coolant mixing with oil is the big one — head gasket. Check the coolant reservoir. If it's brown or oily, walk away. Also check for white smoke on start.

BMW N47 Diesel (1, 3, 5 Series)

Timing chain at the back of the engine. Rattle on cold start = chain about to go. Repair is £2,000+. Always start it cold. If it rattles, walk.

VW/Audi 1.4 TSI, 1.8 TSI, 2.0 TSI

Timing chain tensioner failure and high oil consumption are common. Check oil level on a warm engine. If it's low or black, ask when it was last changed.

Land Rover Discovery / Range Rover

Air suspension, transfer box, and diff problems are expensive. Budget £500-£3,000 for any of them. Check for air suspension warning lights and any leaning.

Nissan Qashqai / Juke 1.6 dCi

DPF (diesel particulate filter) is the Achilles heel. Short journeys kill it. Replacement is £1,000+. Ask how it's used. City only = avoid.

Spanner Jack's 20-Point Viewing Checklist

1. Start it cold. Never let them warm it up first. A cold start reveals rattles, smoke, and rough running.
2. Check all 4 tyre edges — especially the inside. Inner wear = tracking/alignment issues.
3. Open and close every door. Uneven gaps = previous accident damage/bodywork.
4. Lift every carpet edge. Looking for rust, damp, or flood damage.
5. Check the spare wheel well. Water pools there first. Smell it.
6. Run your hand under the sills. Rust bubbles under paint.
7. Pop the bonnet before you drive. Check coolant colour, oil colour, any leaks.
8. Check the service book. Regular stamps from a real garage = good sign.
9. Look at the exhaust smoke on start. White = coolant/head gasket. Blue = burning oil. Both = walk away.
10. Test every switch, window, and light. Electricals are expensive to trace and fix.
11. Check the VIN plate matches the V5. Inside door jamb and windscreen base.
12. Ask to see V5C in the seller's name. If they can't, don't buy.
13. Test drive at motorway speed if possible. Vibrations and pulls only show at speed.
14. Brake hard in a safe place. Any pulling to one side = brake or suspension issue.
15. Turn the steering to full lock both ways. Clunking = worn CV joints. £200-400 each.
16. Check all 4 brake discs through the wheels. Deep grooves = need replacing now.
17. Check the roof lining and sunroof seals. Staining = water ingress.
18. Run free HPI or vehicle history check. Finance outstanding = the car isn't legally theirs to sell.
19. Check the OBD port for fault codes. Get an OBD2 reader (£10 on Amazon) and check before you commit.
20. Never buy without a test drive. Any seller who refuses = instant walk away.

Spanner Jack Answers

The questions every buyer asks. Straight answers.

Should I trust a seller who won't let me inspect it?

No. Full stop. Any seller who says "you can look but not inspect underneath" or won't let you bring a mechanic has something to hide. Walk away — there are thousands of other cars. Your safety and your money are not worth the risk of someone else's hidden rust or concealed accident damage.

What does a clean MOT history actually tell me?

A lot — but not everything. A clean MOT shows consistent maintenance and no major failures year on year. But MOT only tests what's testable at the time. It doesn't mean no expensive bills are coming. Cross-reference the mileage on each test: if it ever goes DOWN, the clock's been wound back. That's fraud.

Should I buy from a dealer or a private seller?

Both can be fine, both can be dodgy. Dealers give you better legal protection under the Consumer Rights Act — you have 30 days to return a faulty car. Private sellers: sold as seen, much harder to get money back. With private, you MUST do a pre-purchase inspection. With dealers, still inspect, but you've got more comeback if it goes wrong.

High mileage or new-ish low mileage — which is better?

Motorway miles at high mileage beats urban low mileage every time. A 120k motorway car with full history is better than a 40k city car with no history. Cars that do short trips never warm up properly — the engine builds up sludge, the DPF clogs, the clutch wears faster. Ask how it's been used. Motorway = wear on the tyres. City = wear on everything else.

What's an OBD2 reader and should I get one?

Yes. Spend £10-15 on Amazon, get a Bluetooth OBD2 reader. Plug it into the port under the dashboard (every car since 2001 has one), run a free app like Torque or OBD Auto Doctor. It reads all fault codes — including pending ones the seller's cleared just before showing you. Spanner Jack rates it as the single best £10 you can spend before buying a used car.

The seller says the engine light is "just the lambda sensor." Should I believe them?

Plug in an OBD reader and find out yourself. Don't take their word for it. Lambda/O2 sensor codes CAN be that simple — but the same symptoms are caused by catalytic converter failure, exhaust leaks, and fuel system issues. A lambda sensor is £20-50. A cat is £200-800+. Verify before you buy. If they've cleared the codes, they'll come back within 20 miles of driving.

Is it worth getting an independent pre-purchase inspection?

For anything over £3,000 — absolutely yes. The AA and RAC offer them. Local trusted garages will do it cheaper (often £50-80). They'll put it on a ramp and look at the underside, test the mechanicals, check the electrics. If the seller won't allow it: red flag. A good car passes an inspection. A dodgy car fails it. Worth every penny.

ADHD brain — I get pressured and panic-buy. What do I do?

Seller pressure is a red flag in itself. "Someone else is viewing it tonight" is the oldest trick in the book. A good car will still be there tomorrow. Bring a friend who can interrupt the pressure. Tell the seller up front: "I don't make decisions on the day." Any seller who won't accept that is a problem. Use Spanner Jack's analysis BEFORE you view so you already know what you're looking for.

Mechanic's Inspection Torch

Check the underside, wheel arches, and engine bay. Rust hides in the dark. Phone torches aren't bright enough.

~£8-12 on Amazon →

🧲

Telescopic Magnetic Pick-Up

Run it along sills and inner arches. If the magnet doesn't stick — that's filler, not metal. Bodywork trick exposed.

🧠 ADHD + Buying a Car

If your brain works differently, car buying is a minefield. Sellers know the tricks. Here's how to protect yourself.

Seller pressure = red flag

Any "someone else is viewing tonight" pressure is manipulation. A good car waits. You do not make decisions under pressure. Full stop.

Bring a script, not just a brain

Print Spanner Jack's 20-point checklist. Work through it mechanically. Tick each box. Your executive function doesn't have to hold everything in memory.

Hyperfocus works FOR you here

Use it. Research the make/model obsessively before you view. Know the common faults. Then Spanner Jack confirms what you already suspect.

Bring a trusted person

Not to decide for you — to interrupt the pressure. "Can we have 5 minutes?" is a full sentence. Any seller who won't give you space is dodgy.
