Nearby Now is a reputation management and review-generation platform rather than a source of editorial car reviews. The page describes a service that helps businesses collect positive customer reviews by sending immediate review requests after a job is completed, with clients reportedly achieving a review response rate above 40%. It integrates with Google Business Profile, Facebook, Twitter, and other platforms, and claims to improve local SEO by building a "reputation footprint" of check-ins and reviews. The platform allows businesses to schedule and export reports on reviews, team activity, and customer data, and offers team leaderboards and live team maps in its mobile apps. It also routes happy customers to preferred local review sites, including Google+ Local, Merchant's Circle, YP, and Angie's List. A sample customer testimonial from "Carissa - Easton, PA" describes "Excellent service." The content is focused on helping businesses gain more reviews, not on providing expert assessments of vehicles such as the Audi S8. Therefore, this source is not useful for evaluating the S8's performance, comfort, or reliability, and no star rating for the car can be derived from it.

REVIEWS.io is an ecommerce review software platform that helps online brands collect, manage, and display verified customer reviews, user-generated content, and survey feedback. The page highlights features such as custom review invitation flows, branded collection pages, AI-powered response suggestions, and analytics that reveal customer preferences and friction points. It explains that businesses can collect both company reviews and product reviews, then display them on websites, emails, and ads to build trust. The service offers a 14-day free trial, month-to-month billing, and flexible plans based on the number of review invitations sent. The FAQ notes that brands can use REVIEWS.io alongside Trustpilot or switch over, with product reviews importable. This is a B2B tool for managing reviews, aimed at merchants and marketers, not a publication that produces automotive road tests. It contains no information about the Audi S8, its engine options, handling, cabin quality, or pricing. Therefore, it cannot provide a rating or substantive assessment of the S8, and no relevant evaluation can be derived from this source.
