What's the best Android app for comparing local car prices and finding a good deal?

CarGurus is the leading app for detailed price comparisons when shopping for a new or used vehicle. Its central feature is the instant market value analysis, which calculates whether a listed price is fair, high, or a good deal relative to similar cars in the local area. This eliminates much of the guesswork for buyers. Users can set up saved searches with specific filters for make, model, price, and distance, receiving notifications when new vehicles matching their criteria are listed. The 'Great Price' badge is a particularly useful visual indicator for deals considered significantly below market value. For real-world use, a buyer could quickly scan a dealership's entire online inventory and identify which specific listings are priced most competitively before even visiting the lot. While the app excels at data presentation, some user feedback suggests the maximum search radius of 500 miles can be limiting for those in remote regions seeking rare models, where a 'province-wide' or more flexible distance filter would be beneficial. The interface cleanly displays critical data like price history graphs, days on market, and dealership ratings aggregated from other buyers. It functions well as a comprehensive research tool before any direct contact with a seller.
