That’s me! With over 20 years in the automotive industry, I’ve always been fascinated by what makes cars tick, and more importantly, what makes them hold their value. Before launching Check Your Spec, I was the Forecast Manager at CAP HPI (think of them as the UK’s Kelley Blue Book), where I led the charge on developing forecasting strategies and depreciation models for all kinds of vehicles. From traditional gas guzzlers to the latest electric vans. I’m particularly proud of the EV forecasting models I pioneered, which are now used by major manufacturers. Basically, if it has wheels and a price tag, I’ve probably predicted its future value! My goal with Check Your Spec is to put that knowledge in your hands, helping you make smarter decisions about the vehicles you want to buy, or already own.
Have questions? Don’t hesitate to reach out via LinkedIn. I’m always happy to help!
Check Your Spec is a free car option valuation tool. You select your vehicle, choose the options and trim fitted to it, and we tell you exactly what each one is worth - today, historically, and in the future. No other free tool does this.
KBB and Edmunds give you a rough overall value based on make, model, mileage, and condition. They don't break down what your individual options are worth. A panoramic roof, an M Sport trim, or a tow package all affect resale, but standard tools ignore them completely. We don't.
The spec valuation tool is completely free and unlimited. No sign up, no email required. Just pick your vehicle, select your options, and see the values instantly.
Check Your Spec was built by Dale Ogden. Dale spent over 20 years in the automotive industry, including as Forecast Manager at CAP HPI - the UK's equivalent of Kelley Blue Book - where he built depreciation models used by major manufacturers. The valuations here are built on that same expertise.
Very. Our values are based on real market data, not manufacturer pricing. We model how options actually perform at resale - not what the brochure says they're worth. Manufacturers and fleet operators use this kind of data to make decisions. So can you.
We update whenever market conditions shift - new models, economic changes, or changes in consumer demand. We don't update on a fixed schedule; we update when the data tells us to.
Three steps. Select your manufacturer and model. Choose the options, trim level, and features fitted to your vehicle. See the valuation instantly in the table below. That's it. No loading screens, no waiting.
Just the make and model. We give you the full list of available options to select from. If you know your trim level (e.g. M Sport, S Line, Raptor), even better, but it's not required.
Yes. You can add any option to see what it would be worth if it were fitted. Useful if you're deciding whether an upgrade is worth paying for, or comparing two different specs before buying.
Yes. For used cars, use the historical columns to find the right model year. For new cars, the future forecast columns show which options are likely to hold their value over the next seven years.
Not through the main valuation tool. Manufacturers don't give anyone API access to option level data tied to a specific VIN - not us, not the big platforms, not anyone outside franchised dealers. What we do offer is a separate VIN decoder that verifies the core vehicle identity and flags recalls, complaints, and ownership risks.
The most reliable sources are: the original window sticker or build sheet (request from the manufacturer using your VIN), your owner's manual, or the manufacturer's archived spec sheets. Our VIN decoder pages for each brand are also a good starting point.
The used value columns show what your selected options are worth right now on a vehicle from each of those model years. So if you're buying or selling a 2021 version of a car, look at the 2021 column to see what those options contribute to the price today.
These are forecasts. They show what we expect your selected options to be worth in the years ahead, based on how similar technology and features have historically depreciated. Useful when you're buying new and want to know which options will hold their value.
Because they genuinely don't add resale value in today's market. A CD player is a good example. Manufacturers used to charge hundreds for them, but buyers don't care anymore. A $0 value isn't a mistake. It means that option won't move the needle when you sell.
Manufacturer pricing and resale value are two different things. Bentley might charge $5,000 for a Bang & Olufsen system. That doesn't mean it adds $5,000 at resale. We value options based on what buyers actually pay for them in the used market - not what was on the original sticker.
Because buyers expect it as standard. Features like automatic emergency braking or lane assist don't command a premium at resale - they're treated as a basic expectation at every price point. Adding value for them would overinflate the numbers.
Each trim level is valued on its specification - the features it includes - not its performance. That means a higher performance trim (like a Porsche Taycan Turbo S) can sometimes show a lower trim value than a more feature laden variant (like the GTS), simply because the GTS has more desirable spec included. It's about content, not horsepower.
Yes. Use the search bar on the right of the options list and type "trim" to see all available trim levels for your chosen model. Or type the trim name directly - "S-Line", "Mach 1", "Raptor", to find and select it.
No. All prices are pre tax.
Trade in is what a dealer offers when you hand your car over - it's the lowest of the three because the dealer needs room to make a profit. Private party is what you'd expect selling directly to another person; usually higher. Dealer retail is what you'd pay buying the same car from a dealership showroom - the highest of the three.
Age, mileage, condition, service history, colour, spec, local market demand, fuel type, safety ratings, and brand reputation all play a role. Options are one piece of the puzzle - but an important one that most tools skip entirely.
Technology moves on. A first generation 360-degree camera added real value in 2018. Now they're standard on most new cars, so the older version is worth less. The same pattern applies to navigation systems, wireless charging, and anything else that was premium once and is now everywhere. We factor this into the future forecast columns.
A small number of logical combinations - like a panoramic roof on a convertible - are excluded because they don't exist in the real world. For anything unusual or specialist, get in touch, and we'll look at it.
Yes. Before you agree a price, run the seller's claimed spec through the tool. It tells you whether the options they're listing actually add value - and how much. It's a quick way to check if the asking price is justified.
Select the vehicle and tick the options the seller is advertising. If the total value of those options is significantly lower than the premium they're charging, you know what to push back on.
Select your model and tick every option your car has. The total gives you a data backed number to reference in your listing and during negotiations. Instead of saying "it's got loads of extras," you can say exactly what they're worth.
It should. Buyers will always try to negotiate down. Having the actual resale value of your spec means you can justify your asking price with real numbers rather than gut feeling.
