There aren't many curated lists of automobiles that include an Aston Martin, a Bentley, a Rolls-Royce, a pair of Lamborghinis, and the Chrysler Pacifica Plug-In Hybrid. Welcome to this month's collection of the least researched vehicles in America.In addition to the aforementioned supercars, luxury sedans, and hybrid minivan are seven models from Audi, three from Cadillac and Lexus, and a lone Mercedes-Benz. We'll do our best to pick out some commonalities, but first, here's the list.Bottom 20 Vehicles Researched In July 2026:Aston Martin DB12Mercedes-Benz CLE 300Audi A5Audi RS 7 PerformanceAudi S5 SportbackAudi S6 Sportback e-tronAudi SQ6 Sportback e-tronCadillac Escalade-VCadillac Lyriq-VChrysler Pacifica Plug-In HybridLexus LC 500 ConvertibleAudi RS Q8 PerformanceCadillac Escalade-V ESVLamborghini FenomenoLexus RC 350Rolls-Royce Black Badge GhostAudi S6Bentley Flying SpurLamborghini UrusLexus RC 300We'll get to the usual glut of Audis, but first, we'll point out that several of the cars on the list have been discontinued. Models like the Pacifica PHEV and Lexus RC may still be sitting for sale on dealer lots, but waning interest is understandable.AdvertisementAdvertisementIt's also not surprising to see ultra-exclusive and very expensive supercars and luxury sedans on the list, including the Aston Martin DB12, Lamborghini Fenomeno and Urus, Rolls-Royce Black Badge Ghost, and Bentley Flying Spur. The Cadillac Escalade-V and its extended ESV sibling have been fixtures on this list, which makes sense considering their extreme prices and limited appeal – SUVs with huge power are fun for a few lunatics (and we mean that in the best way possible), but not particularly practical for the average buyer.And that leaves us with Audi. The German automaker is always heavily represented on this particular list, which we created using data provided exclusively to AutoGuide via AutoFinder.com-an automotive marketplace featuring over 3 million new and used vehicle listings, connecting consumers with top dealerships nationwide to easily find and secure the best deal on a car, truck, or SUV.As always, we attribute Audi's poor search figures to its naming scheme, which makes sense on paper but is difficult to decipher by casual shoppers.
