If you're looking for a luxurious interior for your next top-level sedan, you might be tempted to buy the newest BMW you can afford and quietly call it a day. But suddenly, there's a new player to consider that’s sitting on the lightly used market instead, but which has an interior look and feel that BMW might happily charge six figures for.This 2020 Genesis G90 was the company's full-size flagship when it came out, and Genesis was clearly trying to undercut the S-Class and 7 Series back then at every level. And so, it's interesting to see that you can now buy a used one for the same money as people spend on a nicely optioned new 3 Series.Thanks to depreciation, the G90 is trading somewhere in the low 30s, which is borderline absurd if you look closely at what you get and care more about what you touch than the badge on the grille. This Used Genesis G90 Can Out-Luxe A New BMW On The Inside Genesis Back in 2020, the G90 had a sticker price of just over $72,000 and was clearly the company's flagship, with its twin-turbo V6 or 5.0-liter V8. Inside, observers noted the G90's rich cabin with its Nappa leather, suede, open-pore wood, and metal trim.Genesis included many high-end features as standard rather than burying them in some optional packages and that decision matters a lot when you compare the G90 to modern BMWs. Often, BMW expects you to opt-in if you want genuine leather and some key driver assist or comfort features sit behind expensive bundles.There's a long list of standard features aboard the G90, including heated and ventilated front seats, a powered rear sun shade, a heads-up display and plenty of active safety tech. While if you’re going for a nice 3 Series, you may have to sift through the trim levels or option packages to find many of those items.This makes the value proposition of a used G90 very tempting when you compare it to those German spec sheets, and you won't find thinner padding or cheaper plastics aboard this G90 either, as Genesis didn't cut many corners at all. Instead, this car feels like a strongly overbuilt contender and somewhat similar to an old-school S-Class mindset against today's often compromised reality. Materials, Design, And Tech Make The G90 Feel Truly High-End Genesis Genesis gave the G90 a facelift in 2020 with a serious interior focus. It swapped out the shiny wood for matte open-pore pieces while adding quilted seat inserts and embossing the company's wing logo into places like headrests and rear armrests. The company also redesigned the dashboard and center stack using its horizontal architecture theme.This made the cabin feel somewhat wider and calmer, with those broader and cleaner lines. The 12.3-inch central display also paired with a physical controller on the console, and you could get split-screen capability, sharper graphics, as well as Apple CarPlay and Android Auto, which fixed a major omission from earlier years.As part of the Genesis update, soft touch surfaces ran all the way from the door tops right across the cabin and there was lots of leather, suede, and real metal everywhere to make the back row just as special as the front.Genesis also used active noise cancellation to protect the cabin and its adaptive suspension systems help to actively manage body motions while filtering out the worst that the road surface could throw at you. Reviewers praised the vehicle's quiet ride and smooth power delivery, and Genesis had clearly engineered this car with a comfort-first approach.By contrast, BMW often seems to lean heavily into digital theater with its latest 3 Series. Here you've got a curved display that dominates the dash but a minimalist physical button layout. And while BMW has certainly used a good selection of materials, it has perhaps tried to impress more with its technological approach rather than emphasizing any plush or traditional luxury. Rear Seat Luxury That Embarrasses Brand New German Sedans Cars and Bids Genesis feels that its flagship should be more than capable of chauffeuring executives and VIPs around, and in the G90 you've certainly got a car with rear seat presence. There's lots of legroom and a plush rear bench, while rear occupants have their own power seat adjustments, as well as heating and climate control to play with.They also have a wide armrest with its own switch gear and storage capabilities, and the same level of trim as the front seats. Meanwhile, even though the BMW 3 Series is clearly an excellent sedan in its own right, things are not quite so impressive at the back. The company majors on its front row tech and curved display, but it doesn't necessarily add any special touches behind the B-pillar.The G90 also has a generous trunk with a wide opening and there's a pass-through facility behind the rear armrest for long items. This may be a smart alternative to folding seats, which can sometimes lead to design and quality compromises. What $30,000 Actually Buys You In Today's Used G90 Market Genesis A quick scan across national listings reveals that 2020 G90s have an average price of around $34,000. You may be able to find certain examples for less than $29,000, depending on their mileage and condition, and those vehicles with higher mileage or less desirable colors are right around the $30k window. So, you're not likely to have to hunt for unicorns if you want some genuine flagship hardware for some nice used sedan cash.You may be able to take advantage of some warranty, but you’ll need to read the small print. The company does have a headline 10-year, 100,000-mile powertrain warranty, but this only applies to the original owner, so that won't fully transfer to a second owner through a regular private sale.You might be able to get what's left of any five-year, 60,000-mile new vehicle limited warranty that started on the original in-service date, but in reality, there probably won't be too many cars with that warranty still in place now.Genesis does have a certified pre-owned program, which adds the balance of a 10-year, 100,000-mile powertrain warranty onto certified vehicles.Of course, you can probably expect to pay a price premium versus a non-CPO listing for one of these, and classified listings for 30k G90 examples are most likely to be non-CPO cars. Having said that, it's important to compare new for used as well when you shop and consider whether a smaller or “more basic” new luxury sedan is the better solution when compared to the G90's serious value play. The Trade-Off Versus Buying A New BMW Sedan Today Genesis There are always trade-offs in a story like this, and you'll certainly have to accept that if you do buy a used 2020 G90 versus a new 3 Series, you'll be getting some technology that's a generation out of date. BMW does have those huge, curved displays, advanced driver assist systems, over-the-air updates, and the very latest infotainment software, while on the other side of the equation, the G90 has dual 12.3-inch screens, some updated graphics, and smartphone integration on this model.When it comes to powertrains and efficiency, BMW may also have a stronger story to tell. Its new 3 Series models feature turbo fours or sixes and some of them have mild hybrid systems as well to deliver better fuel economy and give you plenty of strong acceleration when compared to the 2020 G90.In the Genesis, you can get a twin-turbo V6 or a 5.0-liter V8 and while they are smooth and quiet, they don't set the world alight when it comes to efficiency. But if you do a lot of miles each year, then your total cost of ownership equation may start to shift back towards a new BMW.At the end of the day, a 2020 Genesis G90 should be available for roughly the same price as a freshly built compact luxury sedan. And while you certainly won't get a lot of that cutting-edge digital flash if you opt for the G90, you will get plenty of old-school luxury substance to help you enjoy your everyday ride a little bit more.
