CarGurus Analysis: 2018 BMW 4 Series
Summary
With 99 currently listed for sale near Seattle, WA and an average price of $23,190.00, 25.3% of 2018 BMW 4 Series models for sale on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2018 BMW 4 Series 4.92 / 5 stars.
64.6% of 2018 BMW 4 Series models on CarGurus are accident free.
Why it stands out
The 2018 BMW 4 Series stands out as a sleek, premium two-door BMW that was designed to feel more distinctive than the 3 Series models it grew out of. It has a lower, sleeker shape, and BMW also gave it a new body style in the form of the 4 Series Gran Coupe, a five-door hatchback version of the coupe. For buyers who want a stylish used luxury car with a sportier image, that combination of design and body-style variety is a big part of the appeal.
The 2018 model also benefits from the first-generation car’s strong equipment list. Even base models came with 17-inch alloy wheels, xenon headlights, automatic climate control, power front seats and BMW’s iDrive operating system, while the 2017 update brought LED headlights for all models and stiffer suspension for a sharper drive. The lineup included turbocharged four-cylinder and six-cylinder engines, rear-wheel drive or xDrive all-wheel drive, and either a six-speed manual or an eight-speed automatic transmission, so there was plenty of choice for shoppers who wanted a more tailored driving experience.
It is not without compromises, though. The convertible’s folding metal roof adds weight and complexity and takes up some boot space when folded, and BMW repairs can be costly if something goes wrong. Even so, the 2018 BMW 4 Series remains appealing because it combines strong performance, a high-quality interior, and a well-equipped feel with the kind of sporty character that helped set it apart from more conventional luxury coupes and convertibles.

The 2018 BMW is truly a keeper and second to none! This vehicle has everything a serious driver wants or needs on command. I am impressed with its performance, and interior design. The entire vehicle was built for drivers who enjoy the look and feel of luxury and elegance.

You get two cars in one. The hardtop is not being made anymore. A push of a button you go from fun luxury drive to a full open view cruise. The 430 has plenty of power to fly when you want to or when you need to pass. We smile when we get into the car, while we drive it and even when we park it in the garage - knowing we can do it again tomorrow.
