Best and Worst GM Cars

Oh yes, because we just love receiving angry letters from devoted Pontiac Grand Am enthusiasts, we have decided to go there. Based on a heated group Slack conversation, the topic came up about the best and worst GM cars. First of all time, and then those currently on sale, and then just mostly a rambling discussion of Oldsmobiles our parents and grandparents owned (or engineered). Eventually, three of us made the video above. Like it? Maybe we can make more. Many awesome GM cars are definitely going unmentioned here, so please let us know your bests and worsts in the comments below. Mostly, it's important to note that this post largely exists as a vehicle for delivering the above video that dives far deeper into GM's greatest hits and biggest flops, specifically those from the 1980s and 1990s. What you'll find below is a collection of our editors identifying a best current and best-of-all-time choice, plus a worst current and worst-of-all-time choice. Comprehensive it is not, but again, comments. -Senior Editor James Riswick Best Current GM Vehicle Chevrolet Corvette We were flying by the seats of our pants a bit in this first outing and my notes were similarly extemporaneous. When it came time to tie it all together on camera, I failed spectacularly. Thank the maker for text, because this gives me the opportunity to perhaps slightly better explain my convoluted reasoning. I chose the C8 Corvette because it's simply overwhelmingly good, and it's merely the baseline from which this generation of Corvette will be expanded.  While the Cadillac CT5-V Blackwing (more on that in a minute) is an amazing snapshot of GM's current performance standing and its little sibling so enraptured me that I went out and bought one, their existence is fleeting. Corvette will live on; forced-induction Cadillac sport sedans, not so much. So while all three are amazing machines when viewed in a vacuum, the Corvette stands above them as both a reflection of GM's current performance credentials and a signpost of what is to come. So, given the choice between the C8 and the 5V-Blackwing right now, I'd choose the C8. In 10 years, when the Blackwing is no longer in production and Corvette is in its 9th generation? Well, that might be a different story. Now, just pretend I said something even remotely that coherent when we get to the part of the video where I try to make an argument for the 5-V Blackwing as best GM car I've ever driven. Or just laugh at me while I ramble incoherently.

Junkyard Gem: 1984 Pontiac Fiero with supercharged 3800 V6 swap

Like the Corvair, the Vega, and the Citation, the Pontiac Fiero was a very innovative machine that ended up causing General Motors more headaches than happiness, and Fiero aficionados and naysayers continue to beat each other with tire irons (figuratively speaking, I hope) to this day. The General has often proved willing to take the occasional big gamble and huge GM successes in engineering prowess (including the first overhead-valve V8 engine for the masses and the first real-world-usable true automatic transmission) and marketing brilliance (e.g., the Pontiac GTO and related John DeLorean home runs) meant that the idea of a mid-engined sporty economy car (or economical sports car) got a shot from the suits on the 14th floor. Sadly, the Fiero ended up being the marketplace victim of too many issues to get into here, and The General pulled the plug immediately after the 1988-model-year suspension redesign that made the Fiero the sports car it should have been all along. But what if the plastic Pontiac had never suffered from the misery of the gnashy, pokey Iron Duke engine and had been built from the start with a screaming supercharged V6 making way better than 200 horsepower? The final owner of today's Junkyard Gem sought to make that very Fiero, by dropping in one of the many supercharged 3.8-liter V6s installed in 1990s and 2000s GM factory hot rods. The first Fieros came out in 1983 for model year 1984, and the only engine available that year was the Iron Duke 2.5-liter four-cylinder, which generated its 92 horsepower with the full-throated song of a Soviet tractor stuck in the freezing mud of a Polish sugar-beet field. The 2M4 badging stood for "two seats, mid-engine, four cylinders," just as the numbers in the Oldsmobile 4-4-2 once represented "four carburetor barrels, four-speed manual transmission, dual exhaust." This car is a top-trim-level SE model, which listed for $9,599 (about $24,200 today). The no-frills Fiero cost just $7,999 that year, making these cars far cheaper than the only other reasonably affordable new mid-engined car Americans could buy at that time: the $13,990 Bertone (aka Fiat) X1/9. The Toyota MR2 appeared in North America as a 1985 model with a base price of $10,999 and promptly siphoned off the car-buying cash from a bunch of potential Fiero shoppers.

Fiero-based Zimmer Quicksilver was objectively terrible, but we'd totally drive it

Now here's something you don't see everyday. It's listed in our classified ads as a 1986 Pontiac Fiero, but as you can see, that description is a bit misleading. In fact, it's a Zimmer Quicksilver, which was indeed built atop the guts of a mid-engine Fiero coupe but was heavily modified by the Zimmer Motorcars Corporation at a facility in Pompano Beach, Florida. And the one you see here actually seems to be a pretty decent deal for a highly unusual car. We're not sure what was a more popular starting point for kit and custom cars in the 1980s and 1990s, but it would have to be either the Fiero or the vintage air-cooled Volkswagen Beetle. Fiero-based machines usually mimicked the design direction of any number of highly desirable Italian stallions, most commonly, we'd guess, the Lamborghini Countach. The Quicksilver is an altogether different animal, with over a foot of extra wheelbase added in front of the A-pillar to make for a dramatic, long and low silhouette that somehow still only has barely enough room for two passengers in its leather- and wood-lined interior.

A stock 2.8-liter V6 engine from General Motors is mated to a three-speed automatic transmission that sends 140 horsepower and 170 pound-feet of torque to the rear wheels. Period road tests found the 0-60 run took a little over 10 seconds, which is terrible today but wasn't all that bad for the mid '80s. Best we can tell, only around 170 Quicksilvers were made between 1984 and 1988, which are, not coincidentally, the same years that Pontiac produced the Fiero. The 1986 Zimmer Quicksilver you see here is priced at $18,495 and shows well under 30,000 miles on the odometer. There aren't a lot of Zimmer Quicksilvers currently for sale for us to compare, but the ones we did find that had sold within the last few years suggest a little under $20,000 is a reasonable asking price. It could be a fun and offbeat addition to the garage, and if nothing else, you're not likely to see another one at your local car show. Related video: This content is hosted by a third party.
