Hpi clear , 3 owners

Up for sale is my Toyota GR Yaris in Scarlet Flare Circuit Pack— a seriously well-built, high-performance hot hatch that blends OEM+ refinement with aggressive, motorsport-grade upgrades. This car makes 319WHP (approx. 390BHP), tuned by mike from the highly respected SRD Tuning on a SYVECS ECU with 8 custom maps, including low boost, medium boost, high boost, anti-lag, flame map, and anti-theft.

While the engine internals remain standard (not forged), the supporting mods around it are extensive — offering both power and long-term reliability. It's been built with precision, using only top-tier parts, with no corners cut or budget options.

This is a fast, capable, and eye-catching car that’s also perfectly road-mannered when needed. Whether you're after something thrilling for B-roads, weekend meets, track orientated or just want one of the best-looking GRs out there — this one ticks every box.

Final Notes – Why This Car Stands Out:

Let’s be clear — this car isn’t just lightly modified or thrown together with off-the-shelf parts. It’s a meticulously built, well-balanced example that’s been enhanced in all the right areas: performance, reliability, drivability, and aesthetics.

It makes serious power (319whp / approx. 390bhp), but it’s been tuned properly with professional calibration via the Syvecs ECU and multiple selectable maps, so you’ve got full flexibility — from tame and efficient to full send, anti-lag and flame-on.

Every component fitted has been chosen with purpose. No half measures, no unnecessary bling — just quality upgrades from trusted brands and a build philosophy that puts function first.

Unlike many modified cars, this one still behaves itself. It’s smooth on the road, practical enough to enjoy daily, and doesn’t sacrifice comfort or usability. It’s also had paint protection film (PPF) in key areas to keep the finish clean, and the bodywork and interior are in excellent condition throughout, carbon touches give it a unique and premium feel inside and out.

If you're looking for a GR Yaris that's already had the hard work done — properly, cleanly, and with no corners cut — this is the one, You’re not just buying a car — you’re buying a sorted, turn-key build that saves you the hassle, time, and cost of doing it yourself.

It’s not been tracked, abused, or thrown together. This is a serious enthusiast’s car, with tasteful mods and top-tier gear throughout. You won't find many GR Yaris builds this complete and ready to go.

To keep it looking as sharp as it drives, the car recently had a full 2-stage machine polish and professional ceramic coating by Galaxy Detailing Room
