What are the best websites to buy a Mercedes xxx model?

Honestly, navigating the used market for a Mercedes with 20k is all about the data filters. In my experience, Autotrader Used Mercedes-Benz C-Class Search is still the gold standard if you want to dial in specific technical options like the Premium 2 package or lighting packages which real enthusiasts care about. The interface is a bit dated but the inventory depth is basically unmatched. Ive used it for years to track depreciation curves on the W204 and W205 chassis... it really helps you see what a fair price actually looks like over time. On the other hand, CarGurus Used Mercedes-Benz Price Analysis is essential if you're worried about overpaying. Their algorithm calculates if a price is fair based on local Austin market data, which is super helpful when you're in a rush and dont want to get ripped off. Tbh, if you need a car by next week, you should probably focus on local dealers through Cars.com Used Mercedes-Benz Austin Inventory because you can filter by Great Deal and see what's actually sitting on a lot today rather than waiting for a private seller or shipping. CarGurus definitely wins for the pricing data and transparency, while Autotrader is better if you're picky about specific technical specs and interior trim levels. Just make sure to get a pre-purchase inspection before you drop that 20k, especially on a used German car... dont skip that part or you'll regret it later.
