This checklist covers what to look at when inspecting a used car in Ventura or LA County: exterior, interior, engine bay, test drive, and paperwork. You don't need to be a mechanic. Most of what matters is visible if you know where to look and what questions to ask.
Whether you're browsing online or walking a lot in Ventura or LA, take fifteen minutes to go through this list before you commit. It's a small step that can save you a lot of headache later.
Inspect the exterior of any used car
- Check panel gaps and paint match. Uneven lines can mean body work in the past.
- Look for rust around wheel wells, door bottoms, and under the doors.
- Check the tires for even wear. Uneven wear can point to alignment or suspension issues.
- Make sure headlights, turn signals, and brake lights all work.
- Peek underneath for leaks (oil, coolant, transmission fluid).
Inside and electronics
- Run the A/C and heat. In Southern California, you want both working.
- Try the windows, locks, mirrors, and radio or screen.
- Sniff for mustiness or look for water stains (possible flood damage).
- Confirm the mileage matches the listing and any history report you've been given.
Used car test drive checklist
- Drive on city streets and the highway if you can. Listen for odd noises at speed.
- Hit the brakes from moderate speed. Pulling or vibration is worth asking about.
- Pay attention to steering wander or vibration.
- Shift through all the gears.
- Make sure warning lights stay off after startup.
Paperwork and history
- Ask for maintenance records if they have them.
- Check the title status (clean vs. salvage).
- Get clear on what's included: any warranty, return policy, and the full out-the-door price.
At Apollo Auto we encourage questions and test drives. We keep pricing honest and don't tack on hidden fees at the last minute.
Under the hood: what to check without being a mechanic
You don't need automotive expertise to catch obvious warning signs. With the engine off and the car on level ground, pop the hood and spend a few minutes on these:
- Oil level and condition. Pull the dipstick, wipe it, and reinsert. The oil should be between the two marks. The color tells you something too: amber or light brown is normal; very dark or gritty oil means it's overdue for a change, which is minor but worth noting.
- Coolant reservoir. Should be between the MIN and MAX lines. Low coolant can indicate a leak or that maintenance has been neglected. Don't open the cap on a hot engine.
- Battery terminals. Look for blue-green or white corrosion buildup around the terminals. A little is normal; heavy buildup suggests the battery hasn't been serviced in a while.
- Belts. The serpentine belt should look smooth and even, not cracked or frayed. A cracked belt isn't necessarily a dealbreaker, but it's a maintenance item that's coming due.
- Visible fluid leaks. Fresh oil or coolant stains on the engine or on the ground under the car are worth asking about before you sign anything.
What to do if something seems off
Ask about it. A reputable dealer will answer your questions directly and either explain the issue or offer to address it. If something comes up during a test drive or a visual inspection, that's exactly the right moment to bring it up, not after you've signed.
For vehicles over roughly $10,000, a pre-purchase inspection from an independent mechanic (usually $80-$150) is worth every dollar. You take the car to a shop of your choice, they put it on a lift, and they give you a written report. Most sellers, dealers included, will agree to this if they're confident in the vehicle's condition.
At Apollo Auto, we welcome pre-purchase inspections and test drives. Both lots, Simi Valley and El Monte, carry vehicles that have been checked before going on the lot. If you have specific questions about a vehicle's history or condition, Tim can answer them before you make the trip.

High-mileage vehicles: what to focus on
A car with 120,000 or 150,000 miles isn't necessarily a problem. Plenty of vehicles are built to go much further if they've been maintained. But higher mileage shifts where your attention should go:
- Timing belt or timing chain. Ask if the timing belt has been replaced (usually recommended at 60,000-100,000 miles depending on the manufacturer). A timing belt failure is a major repair. Some engines have timing chains, which last longer but aren't maintenance-free.
- Transmission condition. On the test drive, pay attention to how the transmission shifts. Smooth and decisive is good, hesitation or shuddering is not. Automatic transmission fluid should be pinkish-red, not dark brown or burnt-smelling.
- Suspension and steering feel. Higher-mileage vehicles often need struts, bushings, or tie rod ends. You'll feel this as looseness in the steering or a rough ride on even moderate bumps. Not deal-breakers, but factor in the cost.
- Service records. Ask specifically for oil change records. A car with documented regular oil changes at high mileage is a significantly better buy than one without records, regardless of how it looks.
A $100–150 pre-purchase inspection from an independent mechanic is worth it on any high-mileage vehicle over $8,000. Apollo Auto welcomes them at both lots.
