It doesn’t matter whether you’re looking at new or used models; luxury cars can cloud even the most sensible gearhead’s mind.

Few, if any, vehicles depreciate as much as a luxury car. Even the best ones lose a ton of value over time, but the bad ones can literally bankrupt you.

Using trustworthy sources, such as Consumer Reports and J. D. Power, we’ve compiled 13 luxury cars you’ll regret buying — they will have you pulling your hair out as your bank account drains.

E60 BMW M5

Initially, the E60 BMW M5 looked promising. Here we have a car that’s part luxury sedan, part supercar. Step inside, and you’d find all the tech and creature comforts one would expect in that era, and under the hood, it had a massive V10 engine.

The V10 produced tons of power and a glorious soundtrack to match, but unfortunately, it also tended to self-destruct. Ironically, it was crowned engine of the year in 2005, because no one knew it would eat its own rod bearings at that time. All the M5 V10 engines have this problem; owning one will eventually cost a fortune.

E63 BMW M6

BMW launched the E63 M6 in 2005, and, at first, it was an amazing machine. In fact, it was so good it could’ve been among the best BMW M cars ever. Unfortunately, it had the same V10 engine as the M5. In other words, it suffers from a ton of reliability issues.

These cars are total money pits! They have known issues with the rod bearings, valve cover gasket oil leaks, and throttle actuator failure, among other things. It’ll cost thousands of dollars to fix each of these problems. While the car may be running fine when you buy it, at some point, you better prepare to open your wallet wide and max out all the credit cards to keep it in tip-top shape.

F10 BMW M5

After BMW realized that the E60’s V10 engine was suicidal, the Bavarians decided to go back to the tried-and-tested V8. Unfortunately, the F10 BMW M5 came with a laundry list of problems of its own.

Some of its issues were engine-related, but there are also cooling system issues, drivetrain component failures, and suspension component failures. The list goes on. Since this is a high-performance BMW, rest assured that it will cost a fortune to fix.

Maserati Ghibli

Maserati is one of the all-time greats when it comes to building fun and stylish cars. Sadly, the build quality leaves a lot to be desired. This also holds true for the Maserati Ghibli: it certainly looks the part, and when it works, it’s an astonishing Italian GT car. In fact, it’s one of the best in its class.

The problem is that it’s so unreliable, we wouldn’t touch one with a ten-foot pole. In true Maserati fashion, the Ghibli has with both electrical and mechanical issues. It does look stunning, though.

Maserati Quattroporte

Yup, another Maserati; this time, it’s the Quattroporte, which may just be the most stylish sports sedan money can buy. Again, being a Maserati, there will be some issues. Few cars depreciate as fast as Maseratis. These stylish machines are known to be unreliable, and they’re notoriously expensive to maintain.

Due to shoddy build quality, problems can occur after just a few thousand miles. Electrical gremlins are usually the main culprits, but suspension problems, a faulty automatic transmission, and various other issues have also been reported.

Land Rover Range Rover Evoque

Land Rover is famous for its off-road capable vehicles, and the brand is infamous for its reliability issues. The Range Rover Evoque isn’t as off-road-focused as its siblings — it’s designed to attract more stylish, urban buyers. It’s also one of the worst Land Rover products regarding reliability.

There isn’t a specific year or generation that’s bad — all Evoques should be avoided like the plague. They suffer from a variety of engine-related problems, faulty electronics and airbags, faulty turbo, risk of catching fire, and general build quality issues. Some should be covered under warranty, but that only applies to newer models.

Tesla Model S

At first, the Tesla Model S blew the competition out of the water, but like most appliances, the EV didn’t take well to water. Tesla’s Model S suffers from a long list of complicated issues.

At first, Consumer Reports was impressed with the Tesla Model S, so much so that they highly recommended it. Then, in the wake of a storm of reliability issues and complaints, they revoked its “recommended” rating, noting a “worse-than-average overall problem rate.” Dealing with Tesla’s customer service also seems like a nightmare, so we’d steer clear of this one.

E90 BMW 335i

BMW builds some excellent driver-focused cars that are fun, engaging to drive, and offer great handling. It’s easy to see why the Bavarians are among driving enthusiasts’ favorite brands. The E90 BMW 3-Series can be picked up cheap on the used market these days, and few cars can hold a candle to it in the fun department.

One thing to be aware of is that the 335i comes with the N54 engine, a unit that’s known to be troublesome. If you can pick the car up for a song, and you’re capable of fixing it yourself, it may be worth it. If not, move on, as it’ll spend most of its time being worked on.

Jaguar XF

Much like the Italians, British carmakers build some of the best-looking cars money can buy. Unfortunately, it also seems they are just as stumped by electrical systems as the Italians. The Jaguar XF looks great, and the driving experience is what you’d expect from a Jag, and that’s probably why it’s the brand’s best-selling model.

As mentioned, the electrical system is the main problem with the XF, but there’s more. Its interior quality isn’t as good as what the competition offers, and there’ve been problems with the fuel pump and a leaking brake line. The Jag XF has also seen a whopping 19 recalls over the years. According to RepairPal, yearly maintenance will set you back $1,066 on average.

Aston Martin DB9

Few cars are as stylish as the Aston Martin DB9, but while it’s highly desirable, it’s not a car for the faint of heart. Being a British luxury sports car, the DB9 has some issues and it won’t be cheap to own.

Obviously, if you plan to use it daily, you can expect annual maintenance costs to be higher. According to Aston Martin, the average yearly maintenance costs for Aston Martin vehicles range from $4,000 to $20,000, so even on the cheaper end, it’s still expensive. Since its powerful engine is also thirsty, fuel will also set you back a fair amount.

Audi A6

Audi has built some of the best European cars of all time, and there’s no denying that they changed the automotive scenery with the Quattro AWD system in the 1980s. However, the latest A6 does have some problems.

Consumer Reports scored it a paltry 1 out of 5 for reliability, which makes it one of the worst German cars of modern times. It suffers from various electrical gremlins and mechanical issues, and it all seems to stem from an increased amount of tech in modern cars.

Mercedes-Benz CLA

The Mercedes-Benz CLA fails to impress us due to its poor reliability ratings. Considering that the CLA shares a lot of its parts with the entry-level A-class, it’s also pretty expensive for what you get.

Consumer Reports gave the 2022 CLA a poor rating overall due to a low predicted reliability score and owner satisfaction. In fact, it’s the worst-rated luxury vehicle in the entry-level car class, so chances are you’ll regret buying it.

W220 Mercedes-Benz S-Class

The Mercedes-Benz W140 S-class is one of the best and most reliable cars the German manufacturer has ever built. Its successor, the W220, didn’t fare as well. Granted, it had some big shoes to fill, but it failed to measure up to its predecessor in practically every way imaginable.

While the W220 S-class certainly looked good, it suffers from a plethora of reliability issues. Most of them are related to the electronics, but even the air suspension system is known to fail.
