Buying a used car is a balancing act between mileage, price, and long-term reliability. While lower mileage often grabs attention, it’s not the only factor that determines a car’s worth—or its future performance. In this guide, we’ll dissect what “good mileage” really means, expose common myths, and reveal why Simi Valley CDJR’s certified pre-owned (CPO) vehicles offer unmatched peace of mind, even at higher odometer readings.
Understanding Mileage: Beyond the Numbers
The average driver puts 12,000–15,000 miles per year on their car. But mileage alone doesn’t tell the full story. Here’s what truly matters:
1. Age vs. Mileage: The Golden Ratio
A car’s age and mileage should align. For example:
- A 3-year-old car with 45,000 miles (15k/year) is typical.
- A 5-year-old car with 30,000 miles (6k/year) might have hidden issues from sitting unused (Car and Driver).
- A 7-year-old car with 105,000 miles (15k/year) is average but demands a thorough maintenance check.
Simi Valley CDJR Insight: Their CPO inventory includes late-model Jeeps, Rams, and Dodges with mileage that aligns perfectly with their age, ensuring no surprises.
The Mileage Myth: Why 100,000 Miles Isn’t a Death Sentence
High mileage can be a red flag—or a green light, depending on the vehicle. Let’s break it down:
1. Highway vs. City Miles
- Highway Miles: Long, steady drives cause less wear on engines and transmissions. A 2019 Ram 1500 with 80,000 highway miles is often a safer bet than a 2020 model with 40,000 city miles (Edmunds).
- City Miles: Stop-and-go traffic strains brakes, engines, and transmissions.
2. Brand Reliability
- Toyota/Honda: Known for longevity, often exceeding 200,000 miles with basic care (Consumer Reports).
- Jeep/Ram: Built for durability, especially models with the legendary 3.6L Pentastar V6 or Cummins diesel engines (J.D. Power).
- Luxury Brands (BMW, Mercedes): Higher repair costs after 100,000 miles make maintenance history critical.
Simi Valley CDJR Edge: Every CPO Jeep, Ram, or Dodge undergoes a 150-point inspection, ensuring engines, transmissions, and critical components meet strict standards, even at higher mileages.
Mileage Benchmarks: What’s “Good” for Every Age
Use this cheat sheet to evaluate used cars:
| Vehicle Age | Ideal Mileage | Red Flags | Simi Valley CDJR CPO Picks |
|---|---|---|---|
| 1–3 years | 12k–45k miles | Over 50k miles | 2022 Jeep Grand Cherokee (28k miles) |
| 4–7 years | 48k–105k miles | Over 120k miles | 2020 Ram 1500 Big Horn (62k highway miles) |
| 8+ years | 96k–150k miles | Over 175k miles | 2018 Dodge Durango GT (88k miles, tow-ready) |
Red Flags That Outweigh Mileage
Even a low-mileage car can be a lemon if these issues are present:
1. Sparse Maintenance Records
- A 2017 Jeep Wrangler with 60k miles and no oil change history is riskier than a 2015 model with 90k miles and full service logs.
2. Rust or Corrosion
- Check undercarriages and door seams. Cars from snowy or coastal regions may hide rot (NHTSA).
3. Odometer Fraud
- The NHTSA reports over 450,000 vehicles yearly have rolled-back odometers. Always verify with a free CARFAX Report, included with every Simi Valley CDJR CPO vehicle.
When High Mileage is a Smart Buy
1. Diesel Trucks
- A 2019 Ram 2500 with a Cummins turbo diesel engine can easily surpass 300,000 miles with proper care (Ram Trucks).
2. Fleet or Rental Vehicles
- Ex-rental Jeep Cherokees often have highway miles and strict maintenance schedules (Hertz Certified).
3. Certified Pre-Owned (CPO) Programs
- Simi Valley CDJR’s CPO vehicles include:
- 7-Year/100k-Mile Powertrain Warranty: Covers engine, transmission, and drivetrain (Jeep CPO).

FAQ: Your Mileage Questions, Answered
Q: Is 80,000 miles too much for a used car?
A: Not if it’s a well-maintained Jeep or Ram. Simi Valley CDJR’s CPO trucks at 80k miles include warranties for confidence.
Q: How much does mileage affect resale value?
A: Roughly $0.12–$0.15 per mile depreciation (Kelley Blue Book). CPO certification offsets this with added value.
Q: Should I avoid cars over 100k miles?
A: Not if they’re certified. A 2017 Jeep Wrangler with 110k CPO miles is a safer bet than a 2019 model with 50k miles and no warranty.
