* Fastest Car: The title of "fastest production car" changes frequently as manufacturers release new models. Top speed is often tested under ideal conditions, and slight variations in testing can influence results. Currently, contenders for the title often include hypercars from manufacturers like SSC, Koenigsegg, and Bugatti. You'll need to check current automotive news to get the most up-to-date information.
* Most Expensive Car: This is also highly variable. The most expensive car often involves bespoke, one-of-a-kind creations or extremely limited-production models with unique features and materials. The price can depend on the buyer, the specific options chosen, and even the current market conditions. While certain brands (like Rolls-Royce and Bugatti) consistently produce very expensive cars, the title of "most expensive ever sold" is constantly being challenged.
In short, to find the absolute fastest and most expensive cars at any given moment, you need to consult recent automotive news publications and auction results.
