The 1980s and 1990s were an interesting time in automotive history. The straightforward nature of earlier cars was transforming into sophisticated, modern machines. This was especially true with top-tier premium vehicles that today would be labeled as grand tourers that almost approach supercar status. In this Auction Dilemma, we’ll look at two such examples: a 1991 BMW 850i and a 1987 Porsche 928 S4. Both vehicles are up for auction on Cars & Bids.

1991 BMW 850i

Looking to cement a place among the automotive elite, BMW develop the 8 Series to showcase the company’s abilities. While this 1991 850i has seen its share of use (143,000 miles worth) and has a few blemishes, its sleek design and sparkling Brilliant Red exterior make the car a head-turner, even after 30 years.

Of course, the real star of this car is the 12-cylinder engine nestled under the elongated hood. This sophisticated powerplant (when new) boasted 296 horsepower and 332 lb-ft of torque. Ordinary by today’s standards, but attention-getting three decades ago. Anyway, it’s not about brute brawn, but more about subtle strength. A velvet hammer, if you will. Interestingly, this Bimmer relies on a six-speed manual to control the rear wheels, a rarity for the 850i. The seller also reports a Dinan engine tune as well as exhaust and suspension upgrades.

Other than some wear on the driver’s seat, the cabin appears very clean—noteworthy given this car’s age and mileage. In addition to the black leather upholstery, interior goodies include a power sunroof, power fronts seats with Alcantara trim, automatic climate control, and the factory audio system.

The casual car enthusiast may not realize the 928 was developed as a possible replacement for the legendary 911. Porsche management was concerned that the 911 platform was maxed out as the company sought to offer a more luxury-focused product. Fortunately for Porsche fans, the demise of the 911 never happened. This Silver Metallic 928 boasts similar miles (128,000) and scars to its Auction Dilemma counterpart.

The S4 trim debuted in the 1987 model year and featured a reworked 5.0-liter V-8 factory rated for 320 horsepower and 317 lb-ft of torque. This S4 uses a four-speed automatic to manage the rear wheels. The listing mentions that the engine has been rechipped, but performance details aren’t provided.

The burgundy leather interior is classic 80s making the cabin more of a time capsule than anything else. Perhaps the only things impacting this effect are the modest front seat wear and the aftermarket Momo steering wheel. Interior features include a sunroof, heated power front seats, and a Blaupunkt audio system.

While the mechanical condition of top-tier cars from thirty years ago can lead to unpleasant surprises, both of these cars capture the over-the-top formula that German automakers still rely on. With four days remaining on its auction, the BMW 850i has a current high bid of $20,000. Cut those numbers in half for the Porsche 928 S4 with two days left for its auction and a $10,000 best offer.
