Used 2018 Audi A5 for Sale nearLos Angeles, CA

How much does the 2018 Audi A5 cost?

Prices have softened 6.90% compared to this time last year, making it a favorable time to shop this model year.

There are 206 listings available, which suggests you have some room to compare prices and condition across the market.

If you find a listing below $19,012.79, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2018 Audi A5 a good car?

Yes — owners give it 5/5, which is a strong signal that the 2018 Audi A5 delivers on what shoppers want from it.

The review summary points to three recurring strengths: elegant design, impressive handling, and advanced features. It also highlights a sporty yet luxurious feel and a roomy interior compared with competitors, which fits the model’s appeal as a stylish premium car that still works for everyday use.

The overview reinforces that balance by pointing to the redesigned lineup, the practical Sportback body style, and the upscale standard equipment. With 27.7% of listings marked as good or great deals, you also have a decent chance of finding one at a competitive price.

Is the 2018 Audi A5 reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction.

The owner summary also uses reliability-adjacent language in a positive way by emphasizing the car’s overall appeal and noting that many owners appreciate its sporty yet luxurious feel. That said, it also mentions some inconsistency in vehicle condition upon purchase, so the strongest ownership experience is likely to come from a carefully chosen example.

For used buyers, the main long-term risk is less about the model’s appeal and more about whether the specific car was maintained and presented well before it reached the lot.

What should I look for when buying a used 2018 Audi A5?

At 67% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and confirm whether any prior damage was repaired properly. A pre-purchase inspection should be a priority, especially if the car is priced near the low end of the market or shows signs of inconsistent wear.

Focus on overall condition, not just mileage or trim appeal. Because the model’s value depends heavily on presentation and upkeep, you want to pay close attention to paint quality, panel alignment, interior wear, and any signs that the car’s premium features were not maintained consistently.

Is now a good time to buy a used 2018 Audi A5?

This looks like a moderate, selective buyer’s market, where you can shop patiently but still need to move quickly on the best examples.

• Deal availability: 27.7% of listings are priced as good or great deals.
• Inventory: There are 206 listings available.
• Price trend: Prices have softened 6.90% compared with last year.
• Clean inventory: 67.0% of listings are accident-free.

If you find a listing below $19,012.79, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2018 Audi A5's resale value?

The current average of $19,303 sits slightly below last year's $20,735.

That kind of price movement suggests the market has already adjusted downward, which can help you buy more confidently now but may also limit near-term upside if you plan to resell soon. For a future seller, the key is to buy a clean, well-kept example so you preserve as much value as possible.

Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2018 Audi A5 or consider a different year?

If you're weighing the 2018 against nearby model years, here's how to think about it:

Choose the 2018 if:

• 27.7% of listings are priced as good or great deals.
• At 67% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 6.90% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.

The bottom line:

If you want the redesigned A5 with strong owner approval and a softer price than last year, the 2018 is the primary year to target. If you’re especially price-sensitive, keep comparing listings carefully and prioritize condition, because the best value here comes from finding a clean example rather than simply the cheapest one.
