What's the best iOS app for comparing used car prices and history reports?

CarGurus is a dedicated car shopping app that excels in helping users compare prices and access history reports for used vehicles. Its strength lies in features like the 'Fair Price' rating system, which evaluates listings against market data to indicate if a price is high, low, or average, reducing guesswork. Filters for vehicle history—such as accident reports, title status, and service records—are seamlessly integrated into searches, allowing buyers to screen out cars with hidden issues quickly. In practical terms, someone searching for a reliable used SUV under $20,000 can set parameters for budget, mileage, and clean history, with the app displaying detailed listings, dealer reviews, and history summaries side-by-side. User feedback supports this; reviews indicate that the accuracy of descriptions and ease of filtering save significant research time, with one user noting how it helped them find a car swiftly after an accident. However, limitations include a potential skew toward dealer listings in some regions, which might overlook private sales, and occasional gaps in history reports due to reliance on third-party data. The interface, while generally intuitive, can feel dense with filters for newcomers, though it becomes manageable with use. Despite these minor imperfections, CarGurus offers a reliable, transparent platform for car buyers prioritizing value and vehicle history.
