10 Rare Car Accessories That Are Worth A Fortune


Luxury On The Move

If you thought car accessories stopped at fuzzy dice and phone holders, buckle up—you’re about to blast into the rarefied realm of ultra‑luxury add‑ons that cost more than many of us spend on rent. From diamond‑encrusted keys to stretch‑carbon fibre bodies, the rich and famous don’t just accessorize their cars—they turn them into rolling showcases of excess. 

Extra Tesla Car Seats

This accessory is exactly what it sounds like: two extra seats installed in the Tesla Model Y. At a glance, it’s practical—turning the standard five‑seater into a seven‑seater. But these seats come at a price that might make you question your life choices. You get to bring more passengers, but at the cost of trade‑offs in cabin space—they’re a tight squeeze and best suited for kids or very polite friends.

Priced at around $4000, these additional seats transform the Model Y’s seating arrangement for a big chunk of change. While not earth‑shattering, the cost is hefty given that these seats are built into the car’s original configuration—you’re paying extra for convenience and that “Tesla bespoke” touch.

Matching BMW Louis Vuitton Luggage

Luxury doesn’t stop at the car—it extends to what you pack. BMW teamed up with Louis Vuitton to create travel bags that fit the i8’s trunk perfectly. Think: business case, garment bag, travel duffels crafted to the exact specs of the sport hybrid’s storage. You won’t just store your gear—you’ll display it with couture finesse. It’s the epitome of styling for the style‑obsessed car owner.

Pagani Carbon Fibre Body

For the Pagani aficionado who already has “supercar” in their job title, why not go further? This accessory is a full carbon‑fibre body finish for the Huayra—way beyond paint or wrap. It boosts not only visual drama but also adds a 12% gain in torsional rigidity. It’s a sculptural, performance‑boosting upgrade—just one that deepens your bank account significantly.
