Can Octane appraise my car?

We do not provide formal appraisals, but we share our estimate based on comparable sales and our market experience. This gives you a solid starting point.

Are online value check tools reliable for collector cars?

Usually not. These tools are designed for standard used cars and miss the nuances that determine value for special cars, such as rarity, history, and originality.

How large is the gap between asking price and selling price?

This can vary considerably. For collector cars, it is not uncommon for cars to sit for months at an unrealistic asking price. Auction results give a more honest picture.

How does condition affect value?

Enormously. The difference between a car in fair and excellent condition can be tens of percent. Honesty about the condition is therefore crucial.

Does color matter in valuation?

Yes, rare or historically desirable colors can significantly influence value. Some color combinations are much more sought after by collectors than others.

Does a recent restoration always increase value?

Not necessarily. The quality of the restoration and the accompanying documentation are decisive. A poor restoration can actually decrease value.

What if my car is unique and there are no comparable sales?

Then valuation becomes harder. We look at comparable models, the broader market for the brand, and the specific characteristics that make your car special.

How important are matching numbers?

For some models, very important. It confirms originality and can make a significant difference in value, especially for sports cars and rare specifications.

How to Determine Your Collector Car's Value

Why valuation is difficult for collector cars

Collector cars are not standard used vehicles. Their value depends on factors that are hard to quantify: emotional appeal, rarity, history, and market whims. Two seemingly identical cars can differ significantly in price based on their specific story, documentation, and condition.

Additionally, the market for special cars is relatively small. There are fewer transactions than with regular used cars, which means reference points can be scarce. And asking prices are not selling prices. What a car is listed for says little about what is actually paid for it.

Step 1: Research comparable sales

Start by searching for recent sales of comparable cars. Focus on actual transactions, not advertisements or asking prices. Auction results are the most reliable source for this, as they show real market prices.

Where to search

Auction results on Octane and similar platforms
Specialized price guides for classic and special cars
Club forums where members share their sales and purchases
International auction sites for a broader market perspective

Pay close attention to details when comparing. Build year, specification, color, mileage, condition, and documentation all matter. A 911 with matching numbers and a complete service book is a different car from a 911 without history.

Step 2: Honestly assess your own car

This may be the hardest step: looking at your own car objectively. You have memories with it, you have invested in it, and you find it special. But the market looks through different eyes. Assess honestly:

The technical condition and maintenance history
The cosmetic condition, including paint, interior, and underbody
The completeness of documentation and keys
The originality of the car compared to factory specifications
Any modifications and whether they increase or decrease value

Step 3: Understand the current market

The collector car market fluctuates. Models that were hugely popular five years ago may be less desirable now, and vice versa. Economic conditions, generational shifts in buying power, and even cultural trends play a role.

Try to get a feel for the direction of the market for your specific model. Are prices rising, stabilizing, or declining? This helps determine both your expectations and the right timing for a sale.

Step 4: Be realistic about emotional value

Emotional value does not equal market value. The memories, time, and money you have invested in your car do not automatically translate to a higher price. A buyer pays for what the car is now, not for what it means to you.

This may sound harsh, but it is an important insight. Sellers who separate their emotional attachment from the price expectation generally have a smoother selling experience.

Step 5: Seek expert advice

If you are unsure about the value, ask for input from people with market experience. These can be specialists who trade in your make or type, club members who follow the market, or the Octane team that works with these kinds of cars daily.

Multiple opinions help you test your own estimate and discover any blind spots. Be open to feedback, even if it does not match your expectations.

The auction alternative

At auction, you ultimately let the market decide. This can work out surprisingly well if there are multiple interested buyers, but it does require being able to accept the outcome. The combination of a realistic reserve and an honest presentation gives you the best chance of a result you are satisfied with.
