Check this out.... 1 of 1 maybe? 🔥

From what we know this Alfa Romeo 147 GTA is the only one finished in factory white in Aus, making it a truly unique example....

Our goal wasn't just to make it perform better, it was to restore and refine every aspect of the car while enhancing the driving experience!

🔧 Work Completed:
• ARI Performance Custom Headers
• ARI Performance Custom ECU Calibration
• Complete Maintenance Overhaul, Timing Belt, Water Pump, Timing Tensioners & Idlers, Valve Cover Gaskets, etc
• New OEM Spark Plugs & New Bosch Coil Packs
• Full Engine Bay Refresh, Custom Satin Black Engine Bay Components, Polished Intake Runners, Black & Stainless Steel Hardware Throughout
• Countless OEM Parts Replaced & Refinished

Every detail has been considered to bring this GTA back to a standard that does justice to Alfa Romeo's legendary 3.2L Busso V6. A rare car deserves nothing less.

What do you think of the white GTA? 🤍
