Porsche GT4 RS Price: MSRP, Trims & Real-World Cost

The Porsche GT4 RS is the track-focused version of the 718 Cayman, and Porsche sells it as the 718 Cayman GT4 RS. Searches for its price return two very different kinds of number: the starting price from Porsche, and what individual cars have sold for on the used market. This guide shows both and labels each with its model year.

Because the car is built in limited numbers, the sticker price is only a starting point. The Weissach package, which several of the sales below include, changes what a car is worth, and so do mileage, color, and options.

Original MSRP is the manufacturer's suggested retail price. It leaves out destination, taxes, options, and any dealer markup. The 2025 starting price is the headline figure for this page, and the charges that apply on top of it are listed below.

Destination is Porsche's delivery charge and is separate from the starting price. The gas guzzler tax is a federal charge on cars with low fuel economy, and the buyer pays it. Options, paint choices, and packages come on top of all of this. Sales tax, title, registration, and documentation fees depend on your state and are not included in any figure on this page.

Porsche cars are often ordered with a long list of options, so a window sticker can end up well above the starting price. Ask a dealer for the full price on the specific car, including every option, before you compare it with any figure here.

The used market is where many buyers find the car. The rows below are individual sales on Bring a Trailer, an online auction site. Each is a single result for one car on one day, and none is an average.

All four results are above the 2025 starting price. They are also far apart from each other. A 2025 car in Dark Olive Metallic sold for the highest amount on the list, while another 2025 Weissach sold for much less. The two 2023 cars sit at different levels too, with the low-mileage one bringing more. Color, mileage, options, and the mood of that day's bidders all play a part.

These cars sold for more than their original sticker, but that is not guaranteed for every example, and prices can fall as readily as they rise. Check recent completed sales for cars that match the year, package, and mileage you are considering.

• Weissach package. It appears in every sale above, and it is a factor buyers pay attention to.
• Mileage. A car with only a few hundred miles has a different value from one that has been driven.
• Color. Rare factory colors can draw more interest than common ones.
• Model year. The 2023 and 2025 cars in the results sold at different levels.
• Options. Factory options change what a particular car is worth.
• Service history and warranty. Porsche dealer records and any remaining warranty or certified coverage matter to buyers.

Start with a vehicle history report and Porsche service records. Have a specialist who knows these cars perform a pre-purchase inspection, and look at tire wear, brake condition, and any signs of track use. If the car is sold with a warranty, ask how it transfers and what it covers.

Insurance is worth pricing before you buy. Premiums for a car like this can be much higher than for an ordinary vehicle, and quotes vary by driver, age, and location, so ask your insurer about the specific VIN. If you are buying at auction, ask about the buyer's fee, which adds to the total.

This page does not give investment advice. The auction results above show what a few buyers paid, and they do not tell you what any car will be worth later. If you are shopping, set a budget that covers the car, fees, taxes, and insurance, and compare several recent sales for matching cars.
