A Mechanic With 53 Years on the Job Says This Is the Cheapest Muscle Car You Can Buy — Owners With 250,000 Miles Agree

A fourth-generation Pontiac Firebird Trans Am hides a Corvette-derived LS1 V8 under a body style most collectors still overlook. Owners in the comments back the pitch up with odometers past a quarter-million miles. Here is why a mechanic with over five decades on the job calls it the smartest cheap muscle car buy left.

Scotty Kilmer has spent 53 years turning wrenches, and he does not hand out compliments to Detroit iron lightly. So when the internet’s bluntest mechanic pulled up in a fourth-generation Pontiac Firebird Trans Am, grinning like he had just found cash in an old jacket, longtime viewers knew something was different. He was not reviewing a rare survivor or a six-figure restomod — he was pointing a camera at one of the cheapest, most overlooked muscle cars still sitting on used-car lots. The body style is one enthusiasts either love or write off entirely, built during the years Pontiac was fighting for relevance inside a shrinking GM lineup. What Kilmer found under the hood, and what owners piling into the comments confirmed with six-figure odometer readings, is the real reason this Firebird deserves a second look.

In the video, Kilmer walks around a fourth-generation Firebird Trans Am with the enthusiasm of someone who clearly did not expect to like it this much. He calls it flatly one of the cheapest muscle cars a buyer can still find, and spends most of the runtime making the case for why that is a bargain rather than a warning sign. His pitch leans on decades of hands-on repair experience rather than nostalgia: this is a car built around a genuinely serious engine, wrapped in a shape that fell out of collector favor mostly because it is not a Camaro or a Mustang.

The reaction underneath the video turned into its own repair forum. Viewers who currently own or grew up around these cars described daily-driving them well past 200,000 miles, handing them down to family members, and defending the Firebird’s reputation against decades of jokes about Pontiac’s decline. More than one commenter noted that seeing Kilmer this genuinely excited about a car is rare — proof, they argued, that the Firebird still wins over people who walk in expecting to be unimpressed.

The Fourth-Generation Firebird Nobody Expected to Last

Pontiac built the fourth-generation Firebird and Trans Am from 1993 through 2002, the final chapter of a nameplate that had run for 35 years. For most of that run, buyers cross-shopped it against the Chevrolet Camaro it shared a platform with, and the cheapest examples eventually became the used-car-lot afterthought Kilmer is driving in this video. But the final few model years changed the math entirely. Starting in 1998, Pontiac dropped the LS1 — the same 5.7-liter, all-aluminum small-block powering the C5 Corvette — into the Trans Am, replacing the older LT1. A base LS1 Trans Am made 305 horsepower and 335 lb-ft of torque, while the WS6 Ram Air package — with its functional twin hood scoops and 17-inch wheels — pushed the same engine to 320 horsepower and 345 lb-ft, backed by a Tremec T56 six-speed manual or a 4L60E automatic. Earlier fourth-gen cars, from 1993 through 1997, ran the older LT1 small-block and are a different animal mechanically, which is part of why buyers researching this generation need to know which engine sits under the hood before assuming they know what they are getting.

None of that mattered to the market. GM shut down F-body production on the Camaro and Firebird together in 2002, closing the Ste. Therese, Quebec assembly plant that built them and ending the platform for good. That timing is exactly why cars like this one are cheap today: a Corvette-derived V8 wrapped in a body style that fell out of fashion the moment production stopped, sold at a fraction of what the mechanically related Corvette commands. It is the kind of gap that a mechanic who has spent 53 years around cars, as Kilmer describes himself, is uniquely positioned to spot before the rest of the market catches on.

The Maintenance Habit Long-Time Owners Swear By

The comment section under the video turned into its own case study. Several owners described Firebirds well past the 200,000-mile mark still running on their original drivetrains, with one describing a 1997 model purchased at 104,000 miles that has since climbed past 250,000. The habit they credit most often is treating the 4L60E automatic gently around town — avoiding unnecessary overdrive cycling at low speed and staying on top of transmission service instead of ignoring it until something slips. It is unglamorous advice, but it lines up with why this generation of Firebird keeps showing up in driveways decades after Pontiac itself stopped existing as a brand.

Why This Cheap Muscle Car Still Turns Heads Decades Later

What makes the video worth watching is not a rare paint code or a barn-find backstory — it is the argument that the most overlooked Firebirds are also the most honest muscle car buy left on the market. A Corvette-sourced engine, a six-speed or a genuinely durable automatic, and a body style that still turns heads at a gas station, all for used-sedan money. Kilmer’s trademark bluntness works in the car’s favor here: he is not selling anything, he is simply pointing out that the “uncool” muscle car nobody wants is often the one still running two decades and a quarter-million miles later.

There is also a bigger lesson buried in the reaction to this video, one that applies well beyond Pontiac. Enthusiast cars fall out of favor for reasons that have nothing to do with engineering — a badge goes out of fashion, a brand disappears, a body style ages awkwardly for a decade before it circles back into style. The fourth-generation Firebird checked every one of those boxes on its way to becoming cheap, and it is precisely that unfashionable stretch that let genuinely serious hardware trade for pocket change. Buyers willing to look past the styling debate are, in effect, buying LS1 performance at a steep discount to everything else it is mechanically related to.
