I bought this GT4 from a good friend last October with every intention of keeping it long-term—if not forever. It was one of those “finally found the right one” moments. Naturally, I went ahead and spent a good chunk of money dialing it in—motivated by a healthy dose of OCD (as you can probably tell from this ad). That included taking care of a few cosmetic imperfections, followed by full-body PPF and ceramic coating to protect the stunning Gentian Blue paint, plus tint to help preserve the interior.
Then life (and Porsche) had other plans. A few weeks after the car came back from PPF, I got the unexpected call: an allocation for a GT4RS. And as much as I wish I could justify keeping both… I can't. So, this GT4 is now reluctantly up for sale.
The car is in excellent condition, has been well maintained, and needs absolutely nothing. It has what I would consider to be the essential mods for this car (see list below). All service is up to date, and it's ready for someone else to enjoy—whether that's on the twisty backroads or at the track.
This isn't a car I'm trying to flip. It's a car I genuinely love, but I can't drive two at once (sadly). So if you're looking for a well-cared-for, enthusiast-owned GT4 that's been prepped for the long haul, this is the one!

Overview & Highlights
The car is finished in Gentian Blue Metallic over black Leather/Race-Tex with silver stitching—a combination that is both sporty and elegant, and looks even better in person than it does in photos. It's nicely optioned with a mix of comfort and driver-focused bits.
Some of the highlights for me:
- Full Bucket Seats – not super common on 2023s due to a stop-sale earlier in the model year
- Clubsport Headlights – no bumper warts (headlight washers)
- BOSE® Surround Sound
- 2-Zone Automatic Climate Control
- Light Design Package
- Fire extinguisher
- Brake calipers in gloss black
- Power folding mirrors, auto-dimming, rain sensor – all the usual useful stuff
- Steering Column Casing in Leather

Modifications & Add-Ons
The previous owner and myself have done a handful of carefully chosen upgrades, all with the goal of either protecting the car, improving the driving experience, or dialing it in for occasional track use—without compromising street manners. Nothing here was done for show (beside the clear side markers), and everything is fully reversible if that's your preference.
Paint Protection, Tint & Coating
Right after taking delivery, I brought the car to OCDetailing—objectively one of the best shops in the Bay Area (and in my opinion, the best)—for the full treatment. This included a full-body Ultrafit XP Crystal PPF, ceramic coating on all surfaces (paint, trim, wheels, calipers, glass), and 3M Crystalline 70% tint on the side windows, rear hatch, and windshield. The install quality is incredible—full paint correction was done beforehand, all the edges are wrapped and tucked, and you genuinely can't tell the car is wrapped unless you already know.
Interior Protection
I installed EdGuard LWBS bolster protectors and custom headrest covers on day one to avoid the dreaded seat creasing. The quality is outstanding—perfect match to the OEM leather, and you'd never know they're covers unless someone pointed it out. I also added his seatbelt retaining rings, which tidy up the belt routing on the buckets.
Exhaust
The one thing the 718 GT4 really needed was a better exhaust note—and the Flat 6 Motorsports overaxle pipes absolutely deliver. The car now sounds properly alive: not obnoxious, just perfectly balanced.
Handling-Oriented Upgrades
The rest of the upgrades are all about improving consistency and feel on track. The car is still totally comfortable for road use, and nothing here makes it harsh or annoying to drive. These mods just help the car do what it was built to do, more confidently.

Known Flaws
- The Carfax shows a "very minor damage" report on the roof from the previous owner. This was a small dent on the roof. Per the previous owner's account, it was caused by a small object that hit the roof on the freeway. I had it professionally taken care of via paintless dent removal by Ted's Dent Works, one of the best PDR shops in the Bay Area, and have the relevant documentation (before pictures) available.
- Small Imperfections on the Wheels (See Photos)
- Scrapes on the Underside of the Front Lip/Splitter (See Photos)
- Light Scuffs on the Lower Section of the Driver Side Door Panel (See Photos)
- Minor Surface Pitting on the Windshield – Typical, visible if you eyeball the windshield but does not affect visibility.
