In the United Kingdom such companies are members of the British Association for Chemical Specialties (BACS).

Dollar store chain Five Below, the quick-stop market 7-Eleven, and Canadian convenience store chain Alimentation Couche-Tard also earned an F for failing to take action to reduce the use of toxic chemicals and harmful plastics. Changes in temperature could affect the movements of ions across the cell membrane and influence action potentials in that way. You can’t claim a credit for fuel cell property for a second home or for a home that is not located in the United States. Electrical conductivity is a physical property. Offerings comprised standard and DeLuxe fastback and “Touring” notchback four-doors, fastback sedanet coupe, and a revived business coupe. Offerings regrouped to include convertibles, hardtops, and sedans in each series. For mid-’55 came four-door Riviera hardtop sedans in the Special and Century series; Super and Roadmaster versions followed for ’56.

The Riviera name also graced well-proportioned 1950-51 Super and Roadmaster four-door sedans with special long wheelbases (125.5 and 130.3 inches, respectively). Century and Special also offered new all-steel four-door Estate wagons (remarkably with no ersatz wood). These (along with the Oldsmobile Holiday) were the first four-door hardtops, GM once again forcing the rest of the industry to play catch-up. Yet despite the most-sweeping alterations since ’49, Buick’s ’57s didn’t sell that well, mainly because rivals were pressing hard for industry design leadership. The ’56 Buicks didn’t sell as well as the ’55s — but then, ’56 was a “breather” for most everyone. The XP-300, on an inch-shorter wheelbase, prefigured production ’54 Buicks in its frontal treatment. The “horsepower race” was at full gallop, and the ’56s were the most-power­ful Buicks yet. All 1950-52 Buicks and the ’53 Special continued to rely on aging but proven valve-in-head straight eights. Both used an experimental 215-cid aluminum V-8, a very special job unrelated to Buick’s same-size early-’60s engine.

Overall, it somewhat resembled Buick’s ’54 Wildcat II show car, but was evidently less-impressive than the ’53 Skylark, for only 836 were sold before the model was dropped. Much of Buick’s 1954 styling was previewed by the XP-300 and 1951 LeSabre show cars, rolling testbeds for numerous postwar GM ideas. Another facelift introduced model-year designation to exterior nameplates, which Buick would abandon after 1957 amid customer complaints that it made the cars obsolete that much sooner. The Special now offered 220 bhp, other models 255. A Century could leap from 0-60 mph in 10.5 seconds and top 110 mph, and every ’56 Buick could do at least 100 mph. The 1950 Special engine delivered 115 bhp (120 bhp with Dynaflow) from its usual 248 cid. Dynaflow (some called it “Dyna-slush”) had been an increasingly popular Super/Special option since 1950 (it remained standard on Roadmaster). Like 1953’s corresponding Olds Fiesta and Cadillac Eldorado, Skylark was basically a customized standard convertible, with four-inch lower windshield and top, plus fully radiused rear wheel cutouts. Skylark was another of those long-famous Harley Earl styling projects, but was planned for the broadest possible appeal. Skylark also returned for ’54, but was much less “custom” than the ’53, though that enabled Buick to trim price down to $4483.

Though division general manager Ed Ragsdale never said how much this makeover cost, it must have run several hundred million. Without curbside pick up, the waste must be taken to a recycling center or dumpsite and paid for by the ton. The Shark Stratos immediately wowed us during testing, picking up hair without tangling and seamlessly tackling dust and debris, earning its spot as our top pick next to the Dyson Gen5detect as an equally great but more accessible choice. To avoid harming the fabric, stop tamping as soon as the spot is removed. Displacement, compression, and power varied with model and year. With exactly square dimensions (3.25-inch bore and stroke), 10:1 compression, and a Roots-type supercharger, it produced over 300 bhp — phenomenal for the day. Over 380,000 were built for 1955, Detroit’s banner year of the decade, including 155,000 Riviera two-door hardtops, that season’s single bestselling Buick. Also highlighting Buick’s 50th year was a flashy new limited-edition Roadmaster convertible. The ’53 Roadmaster Estate cost a hefty $4031 and weighed 4315 pounds. Both lines also included woody Estate wagons through ’53, with struc­tural body parts of mahogany and white ash.
