Should You Detail Your Engine Before Selling?
A clean exterior sells cars—but what about the engine bay? Here’s why engine detailing can boost resale value.
When preparing to sell a car, most owners focus on paint, wheels, and interiors. But savvy buyers (and dealers) also look under the hood. A dirty, greasy engine bay suggests poor maintenance, while a clean bay signals care. The question is: should you detail your engine before selling? Let’s explore the pros, cons, and best practices.
Why a Clean Engine Bay Helps Resale
- ✅ First Impressions: Buyers see a cared-for vehicle.
- ✅ Trust Factor: Clean engines suggest proper maintenance.
- ✅ Dealer Value: Trade-ins with clean bays often fetch more.
- ✅ Photos Sell Cars: A clean engine makes online listings pop.
When Not to Detail Your Engine
In rare cases, aggressive cleaning right before a sale can raise suspicion. Buyers may wonder if you’re covering up oil leaks or mechanical issues. Keep it natural—aim for a fresh but not overly dressed look.
