I'd Buy a 150,000-km Lexus Over a 50,000-km BMW. Here's the Math.

Standard scene. Budget €23k. Walk into the used lot. The salesman shows you two cars.

One is a 2020 BMW 330i, 48,000 km, last facelift G20, full BMW history, looks like nothing has touched it. The other is a 2014 Lexus IS 300h, 158,000 km, two owners, full Lexus history, slightly older interior, smells faintly of perfectionism.

Most people walk straight past the Lexus. They're wrong, and I'll show you why.

What you actually buy when you buy a "low-km BMW"

A 2020 BMW 330i G20 at €23k with 48k km has not finished depreciating. It's at year five, which is the part of a German premium car's curve where it goes from "almost new" to "okay used" and loses another €6,000–€8,000 in the next 36 months. That isn't speculation — it's the standard depreciation curve every BMW dealer has on a spreadsheet.

You also inherit:

• A B48 engine that's solid, but the timing chain on early G20s is being watched.
• A ZF8 transmission that demands its first fluid service around 80–100k km (€450 at a specialist).
• A run-flat tire setup that costs €1,400 a set and gives you 25,000 km if you're nice.
• An interior that depreciates faster than the drivetrain because everyone notices iDrive 7 vs iDrive 8.

You're going to spend, conservatively, €11,000 in depreciation + maintenance over the next five years. At the end of that you have a 2020 BMW 330i with 110k km worth around €12,000–€13,000.

I'm not making this scary. I'm making it visible.

What you actually buy when you buy a "high-km Lexus"

The 2014 IS 300h at 158k km is at the bottom of its depreciation curve. It has already done what cars do. From here the value moves with mileage and condition, not with the calendar.

The 2AR-FXE Atkinson-cycle 2.5 hybrid inside it is one of Toyota's most boring engines, and that's a compliment. No turbo. No DPF. No DSG. No EGR clogging. No charge pipe to crack. The transmission is an electric CVT that has, in fifteen years on the road globally, produced essentially zero forum-thread failures. The battery is a NiMH pack engineered to outlast the car — when they do degrade, refurbishment kits are €1,500 from a dozen specialists across Europe.

Your five-year hold on this car: maybe €1,500 in actual maintenance beyond consumables (one set of tires, brake fluid, gearbox cooler flush, hybrid coolant). And by year five you've got a 2014 IS 300h at 208,000 km worth around €11,000–€13,000.

Side-by-side math

Same starting point, five years out:

That's nearly €4,000 of real money that stays in your account if you buy the Lexus.

And — this is the part nobody mentions — the Lexus does that with fewer headaches. You don't wake up wondering whether your timing chain rattle is "normal." You don't read forum threads at 2 AM. You don't look up "ZF8 mechatronic refurb cost." You just drive it.

The objections, answered

"But the BMW is faster."

330i: 0–100 in 5.8 seconds, 258 hp. IS 300h: 0–100 in 8.3 seconds, 223 hp combined.

Yes. The BMW will go to a German motorway top speed faster. In every other situation — A-roads, city traffic, school run, going to Ikea — the difference is 2.5 seconds at full throttle. If you can spend €4,000 to buy back 2.5 seconds you'll use four times a year, that's your call.

"The Lexus looks dated."

Inside, yes. Outside, the 3IS facelift (2017+) is honestly handsome and looked timeless when launched. The infotainment is the worst part. The drive-mode haptic dial is fine. You'll get used to the trackpad in three days.

"Resale on a high-km car is going to be a problem."

It actually isn't, because the curve has flattened. A 208,000-km IS 300h in 2031 will trade for €10–12k in the EU because the buyer market knows the drivetrain doesn't care. The 330i at 110k km in 2031? Trades on condition and history because the buyer is gambling on the maintenance YOU did. Lexus owners gamble less.

"What about the hybrid battery."

Toyota Hybrid Synergy Drive (which Lexus uses across IS/ES/RX/NX) has the most-tested traction battery in the world. Empirical lifespan: 250,000–400,000 km in normal service. Failure modes are gradual (degraded capacity) not catastrophic. Replacement at a specialist is €1,500–€2,500 in 2026. You'll likely never see it.

When the BMW wins

It's not always the wrong call.

• You drive 35,000+ km a year and need a comfortable motorway car — 330d > IS 300h on this brief. (Note: 330d, not 330i.)
• You actually care about handling. The 330i has real chassis depth that the IS just doesn't. If your weekend is about a good road, drive the BMW.
• You can do your own work. A lot of the maintenance premium on the BMW disappears if you turn your own wrench. The Lexus is hard to make cheaper because there's nothing to do.
• You change cars every 2 years anyway. Then depreciation curves don't matter.

For everyone else — daily driver, family car, total-cost-of-ownership conscious, generally doesn't want to think about the car — the Lexus is the rational pick by an embarrassingly large margin.

What to look at when you go see one

If I've convinced you, here's what matters:

• Service history. Lexus dealers in the EU are pedantic. Continuous Lexus stamps until at least 100k km is what you want. If the last few stamps are at an indie, that's also fine, but ask whether they did the brake fluid every 2 years.
• Battery state of health. Any Lexus tech can run a diagnostic in 15 minutes. You want SOH above 70%. Below that, factor a refurb into your offer.
• Inverter coolant. Should have been changed once around 100k km. Pink liquid in the reservoir. If it looks black or has never been touched, deduct €200.
• Transmission cooler. On RWD hybrids these can develop seepage at ~150k km. Ask to see the gearbox dry from below.
• Tyre wear pattern. Even wear = aligned, decent suspension. Uneven = something's tired.

None of this takes 15 minutes. None of it is unusual for a 150k-km car. The car you're not looking at — the low-km BMW — has the same number of things to check, but they're scattered across more failure modes and the seller knows less about them.

The honest end

I drive a German car. I'm not anti-BMW. I'm just adding up the actual money.

If you treat your car like a 5-year tool that should run well and not surprise you, the IS 300h is a smarter use of €23k than the 330i. The same logic puts you in an ES 300h at €27k or an RX 450h at €30k instead of equivalent E-Class or X3 spend.

The lower-km German car looks like the safer bet. It just isn't.
