Checking the Air Ride That Makes it Comfy.

This is a big one to check. Most Discovery 3s have air suspension. Instead of normal metal springs, they use bags filled with air. This gives that smooth ride. But this system can break, and it costs a lot to fix.

Here’s what to simply check:

• Does it go up and down? Start the car. Ask the seller to show you, or find the button yourself (near the gears). Make the car go up to its highest setting, then down to its lowest. It should move smoothly. It shouldn't take ages.
• Listen to the air pump. You should hear a humming sound when the car is lifting. That's the pump filling the airbags. It should sound steady, not loud or rough. It shouldn't run all the time.
• Does it sit flat? Look at the car from the side and back. Does it look level? Or is one corner lower than the others? If it looks wonky, there could be a leak in an airbag or pipe. Ask the seller if the car ever drops down on its own when it's parked for a while (like overnight).
• Any warning lights? Look at the dashboard. Is there a light saying 'Suspension Fault'? Don't ignore this! Even if the seller says it's nothing, it means something is wrong. It could be simple, or it could be expensive.

Looking at the Engine, especially the Diesel

The diesel engine (the TDV6) is the most common. It's a strong engine, but it needs looking after, and some things can go very wrong.

• Ask about Timing Belts: This is super important. These belts inside the engine need to be changed after a certain number of miles or years (ask the seller when they were last done). You MUST see proof this job was done – like a bill or a stamp in the service book. If they haven't been done, and they are due, you MUST get them done straight away. If a belt snaps, it can wreck the engine. This job costs quite a bit of money.
• Listen for Bad Engine Noises: Some of these engines have had a really bad problem where a main part inside breaks (called the crankshaft). This costs a huge money to fix, like needing a whole new engine. It's hard to know if it will happen, but listen carefully when the engine is running. Do you hear any deep knocking or rumbling sounds from the bottom of the engine? If you do, walk away.
• Check for Running Problems: Parts called EGR valves (they help with pollution) can get blocked up. This makes the engine run rough or lose power. Fixing them costs money.
• Look for Leaking Oil: Peek under the car and around the engine. Can you see oily patches? Ask where they are coming from.
• Try to start the engine when it's cold: Does it start easily? Does it sound smooth or rough? Are there any bad rattles or smoke? A good engine should start easily and sound reasonably quiet (for a diesel).

Checking How the Automatic Gears Feel

Most Discovery 3s have automatic gears. These should make driving feel smooth and easy.

When you take the car for a test drive, pay attention to the gear changes. As you speed up and slow down, the changes should happen almost without you noticing. You shouldn't feel any sudden bangs, hard thumps, or long pauses when the gears shift. Also, listen for any strange whining or grinding sounds coming from the gearbox area under the car. When you park, have a quick look underneath for any drips of oil, especially reddish or brownish oil, which could be from the gearbox.

Looking Over the Car's Body for Rust or Old Damage

The Discovery 3 is built like a tank underneath, but the bodywork on top can still get rusty or damaged over time.

You need to look carefully for rust. Check around the edges of the wheel arches, especially the ones at the back. Look along the bottom edges of the doors and the big rear tailgate (the boot door), particularly around the handle area. It's also wise to try and look underneath the car at the metal frame and suspension parts for serious rust. A little bit of surface rust might be okay and treatable, but big flaky patches or holes are bad news and expensive to fix properly.

Checking Inside the Car

The inside of the Discovery 3 is usually a nice place to be. Check how worn it looks.

• Look at the seats. Are they ripped or badly cracked? The driver's seat usually shows wear first. If it has the extra seats in the boot, make sure they fold up and down easily.
• Look at the roof lining. Is the fabric hanging down anywhere? This happens sometimes and is annoying to fix. If it has sunroofs, check around them for wet patches – that means they might leak.
• Feel the carpets. Lift the mats and feel the carpet, especially in the front where your feet go and in the boot. Does it feel damp? Water getting in is bad. It can cause smells and electrical problems.
• Look at the steering wheel and pedals. Do they look very worn? If the car says it has low miles, but the steering wheel is shiny and worn, maybe the miles aren't right.
• Press all the buttons. Check all the switches inside work – heating controls, window switches, everything.

Taking It For a Drive

The test drive is super important. This is your chance to feel how the car behaves on the road. Try to drive it on different kinds of roads if possible – slow town roads, faster main roads, and maybe find a bumpy bit too.

Where Can You Find a Discovery 3 to Buy?

You'll see Discovery 3s for sale in a few different places. Official Land Rover main dealers might sometimes have older ones, but they will likely be the most expensive. Independent garages that specialise only in Land Rovers can be a great place to look. They usually know the cars inside out, check them thoroughly, and might offer a decent warranty. They often charge a bit less than main dealers.

Don't Be Rushed, Take Your Time, and Maybe Get Expert Help

The most important tip is probably: don't rush into buying the first Discovery 3 you see. Try to look at two or three if you can, so you can compare them.

Also, think very seriously about paying for an independent inspection before you buy. This means you pay a mechanic, ideally one who specialises in Land Rovers, to give the car a thorough check-over for you. They'll look at everything, plug in a computer to check for hidden faults, and give you a report. It might cost you £150, £200, maybe £300, but it could save you thousands in the long run by spotting expensive problems before you commit. It's often money very well spent for peace of mind.
