It was meant to be simple.
Just two cars. One test. A clear winner. We’d been itching to stack these against each other since the Lexus SC430 rolled off the line. The specs matched like puzzle pieces. Price? Almost identical. Power-to-weight? Locked in. Performance numbers? Dead even.
But why only two? You might ask where the Jaguar XK8 is. Or the Porsche 911 cabrio. Sure they exist. Sure they’re cool. But let’s talk money. The Jag starts around $76,000. The Porsche sits at $80k. Our contenders? Roughly $61k each. The expensive guys stayed home. We stick to budget. Or we try to.
Then the weather ruined it.
Our Mercedes-Benz CLK430 was parked in Atlanta. Just one in the fleet. And Atlanta? It was freezing. Sleet, snow, slush. Not exactly wind-in-your-hair testing conditions. We considered Florida, but the roads there are statistically flat. Boring. Like a lecture on statistics without the caffeine. Our guy Bedard put it bluntly.
It’s an excellent place to check out steering feel.
Great. We drove through the dead zone of Spring Break traffic to get there anyway. Skin, parties, noise—none of that matters when you are driving 1,640 miles. From Atlanta to the panhandle, down to Ft. Myers, across to West Palm Beach, up to St. Augustine, back to Atlanta. It was basically One Lap of Florida. With extra schlepping.
The result? We knew every squeak and groan in these cars by the time we dropped them off at Hartsfield International. The gap was paper-thin. But in every tight contest, someone bleeds less. Here, it wasn’t a surprise who took the crown.
Second Place: Lexus SC430
On paper? The Lexus won almost everything. Faster acceleration. Quicker emergency lane changes. Better skidpad numbers. It stopped better too—on the first lap anyway. Then the brake pads caught fire. Repeatedly. You learn to brake earlier in Stuttgart-branded cars, apparently, because the Lexus stayed firm where the Benz faded into oblivion.
It also came with more stuff. A satellite navigation system. An in-dash CD changer. A folding hardtop that moves like aluminum origami. Mercedes pioneered the hardtop convertible revival, sure, but the CLK uses fabric. The Lexus uses steel and glass.
So why is the Lexus in second place?
Style. Dynamics.
Subjective things. Things the market disagrees on. The only car that got more positive vibes from us recently was the Audi TT. The rest? Uniform indifference.
The SC430 isn’t a sports car. It doesn’t pretend to be. It is a Grand Tourer. Fast? Yes. Sporty? Marginally. At home on a track? Never. Our vague preference for Mercedes turned into certainty the moment we hit a corner. The Lexus wallowed. Lifeboat-style body roll. Relentless understeer. It refused to commit.
The seats betrayed us. “Clubroom” front seats meant no lateral support. When the g-forces hit, you gripped the wheel to stay centered, not because you enjoyed it. The ride? Softer than expected. The Dunlop tires on this car helped. Usually, Lexus pushes run-flats to save trunk space for… nothing, since there is no trunk. Sharp bumps translated as harsh thuds through a relaxed chassis. Disappointing.
Under the hood? The 4.3-liter V-8 was sweet. VVT-i tech gave it 300 horsepower. 325 lb-ft of torque. Twenty-five horses more than the Benz. It revved cleanly. Quietly. Always Lexus’s strong suit.
Inside? Sumptuous. Genuine walnut. Good leather. A tilting, telescoping steering wheel. The touch screen nav left fingerprints like a crime scene, but it worked.
The back seat? Useless. Lexus calls it a “2+2”. You could fit two hobbits if you folded their legs up. The trunk was equally tight. The top mechanism eats space. The Benz loses the speed war there—the SC raises the top 7.3 seconds faster, lowers it 3.3 seconds faster. But does it look cool without it?
We argued it looks like a Buick. Not a Buick sedan, but in spirit. A heavy, plush cruiser. One tester asked, “Is this the next Riviera?”
Highs: Punchy engine. Quiet cabin. Fancy interior.
Lows: Lazy handling. Weird proportions. Bad back seats.
Verdict: If you want relaxed sportiness, this is it.
First Place: Mercedes-Benz CLK430
The last CLK cabrio we tested had a V-6. It won for style. This one has AMG wheels and a V-8. The heart of our testers? Still captivated.
Power-wise? It kept pace. 275 hp versus Lexus’s 300. It hit 60 in 6.7 seconds. The Lexus was 0.1 faster. Barely. But the exhaust note had menace. It sounded German. Dangerous.
Chassis? Stiff. Built on a C-class base. We tested that platform in ’98. It won on rigidity then. It wins now. The Lexus shuddered over rough pavement. The Mercedes ignored it.
Stiffness equals handling. And that paid off. On the Moroso track, the Benz rotated. It slid over the apex. It had attitude. The ESP stability control nagged, even when off, but the car was willing. The Lexus was doggedly resistant. The Touch Shift transmission gave a illusion of control, though manual gear selection felt clunky at best.
Braking? Still an issue. You had to avoid the panic button to avoid the fade. The Lexus rear rotors are bigger (12.1 vs 11.4 inches) and felt more decisive. Steering adjustment on the Benz is limited, too—telescoping only, no tilt. The seats, however? They hug you. Real support. The Lexus seats were chairs; the Mercedes seats were molds.
Inside, though? It felt sparse. Bird’s-eye maple and leather looked severe compared to the Lexus’s opulence. The wind blocker stored in the trunk is a nuisance to install but kills the turbulence. The rear window is a narrow slot. Visibility is poor.
But the soft top? Beautiful. Lined. Silent when up. And the look? Cool, whether the top was up or down. It didn’t demand attention like the Lexus did, which tried too hard to be seen. It just looked… classic.
Highs: Athletic balance. Good seats. Four usable spots. Looks.
Lows: Spartan interior. Clunky shifters. Weak rear glass. Mushy brakes.
Verdict: German dynamics won.
The Bottom Line
Price-to-value? The Lexus wins. You get navigation and more tech. The Mercedes adds a useless phone and a trunk-mounted CD changer for $2,000. Prestige? People still think the Benz star packs a punch. Or maybe they just think Lexus has enough class now.
Doesn’t matter.
One car was built for driving. The other for cruising. The other is designed to be noticed while you do neither.
Which one sounds more important?
We know our choice.
