List price and value drop for Porsche Cayman Gts

Choose a model year to see the list price and an indicative used-car value today. Based on official OFV list prices (2015), assuming 15 000 km per year. Cars typically lose the most value in the first few years, then depreciation slows — it's not a fixed amount each year.

Questions

Frequently asked questions

How many Porsche cars are registered in Norway?
According to SSB (2025), 19,790 Porsche cars are registered in Norway (0.7% of all passenger cars). We use market data and inspection history when valuing your Porsche.
What is a Porsche Cayman Gts worth?
Sonja lets dealers bid on a Porsche Cayman Gts in a time-limited auction. The price is set by competition — photos and a self-declaration are the documentation. You choose whether to sell.
How much does it cost to use Sonja?
Using Sonja costs nothing: prep, review and the auction are free. We charge a fee from the buying dealer — you as the seller pay nothing. The offer applies to the specific car you enter in the form.
Do I have to drop the car off somewhere?
No. The car stays with you. We need photos and a few answers. If you accept the highest bid, we arrange collection.
How quickly does the auction start?
Finish photos and answers today, and the auction can start and end tomorrow. It normally starts the next weekday at 09:00 and runs the same day. Then you have the highest bid ready, and can in theory sell the car tomorrow. You have plenty of time to accept or decline.
Which cars can I list?
Most Porsche Cayman Gts cars can be listed in the auction. We assess year, mileage and condition for the specific car — submit the form and we will help you next.
What is the difference from a private sale?
A private sale means listing the car, filtering inquiries and having strangers visit your home for viewings. With Sonja, dealers bid in a time-limited auction. You choose whether to sell — at no cost if you decline.
How much did the Porsche Cayman Gts cost new?
We show indicative list prices (new) for the Porsche Cayman Gts from OFV on this page. The new list price is one of several reference points dealers use when assessing what the used car is worth today.
Does Sonja use EU inspection data for the Porsche Cayman Gts in its assessment?
Yes. Historical PKK data (periodic vehicle inspection) for the Porsche Cayman Gts is one of several factors dealers look at. It gives a clearer picture of the model's typical technical condition over time.
What do I need to do to sell my car?
Enter your registration number and mileage. We pull technical and ownership data from the road authority automatically. Then you prepare the car at home with photos and a self-declaration. Finish those two steps, and the auction can start and end tomorrow — then you have the highest bid ready.
