The build: a textbook full bolt-on EJ257
Prime Driven's Giveaway #308 car is a 2015 WRX STI — first year of the VA chassis, last hurrah of the EJ257 2.5-liter turbo flat-four. The parts list reads like a forum build thread done right: COBB Accessport V3, TurboXS front-mount intercooler, ID1050X injectors fed by an AEM 340LPH pump, COBB boost control solenoid, MAPerformance intake, and a Perrin catted downpipe breathing into an Invidia Q300. HKS Hipermax coilovers handle the suspension. Prime Driven quotes only the factory rating — 305 hp / 290 lb-ft — and publishes no dyno sheet, but that supporting hardware exists to run more boost than stock. Credit where due: they also publish a compression test, 160 psi across all four cylinders, which is exactly what you want to see on a 136,000-mile EJ.
Why it matters: odds you can actually calculate
Most giveaways bury the entry pool size; this one caps it at 2,000 entries with a 25-per-person limit, so a single $25 entry is worst-case 1-in-2,000. The honest counterweight: this is a roughly $13,000 car. High mileage, heavily modified, and the tuned EJ257's ringland-and-head-gasket reputation is earned — whoever wins should budget for the engine's eventual appetite. The $8,000 cash alternative is a legitimate option to weigh against a 136k-mile project-adjacent STI.
The fine print worth knowing
The sweepstakes runs June 11-15, 2026 (ends 11:59:59 p.m. PST per the rules) or closes early the moment 2,000 entries fill — Prime Driven says its giveaways typically fill in under four days, and this one was 28% claimed at time of writing. Every $25 spent in the shop earns one entry; digital posters run $25 (1 entry) to $200 (8 entries). The free route is a hand-printed 3x5 card mailed to the sponsor, postmarked by June 15 and received by June 20. Open to U.S. residents 18+ except Alaska, Florida, Hawaii, and New York. Drawing is conducted on or about June 22, 2026 by third-party administrator American Sweepstakes and Promotion Co. Winner pays all taxes on the prize.

Why It's Special
Nothing collector-grade here — a driver-condition, high-mileage VA-chassis STI. The 2015 model year is notable mainly as the first of the VA generation still carrying the long-serving EJ257; the draw of this giveaway is the hard 2,000-entry cap, not scarcity of the car.
Our value estimate
$13,500
Sponsor's official rules state a $13,000 ARV and an $8,000 cash alternative. KBB private-party range for a typical-mileage 2015 STI runs ~$13.5k-$17.3k; this car's ~136,000 miles sit well above typical, and tuned EJ257s trade at a discount to stock regardless of parts spend. Top-of-market contrast: a modified 47k-mile 2015 STI asked ~$26k on Cars & Bids (Aug 2025). Netting high mileage against the bolt-on list and the published 160 psi compression across all cylinders: ~$13,500 — essentially endorsing the sponsor's ARV. Editorial estimate, not an appraisal.
