The 1984 Alpina B9 3.5/1 is a rare and distinctive vehicle, with only around 500 units produced from BMW's E28 platform. This particular B9, serial number 469, hails from the 1980s and features an upgraded 3.5-liter inline-six engine. The engine benefits from Alpina's modifications such as a reworked cylinder head, performance-tuned camshaft, Motronic remapping, and Mahle pistons. This results in an exciting driving experience, encapsulated by the B9's iconic sedan body-style.
