In this episode of Restore It, I continue with the BMW E30 325i Touring restoration. Key tasks include removing the rusty driver's side door for welding or replacement, as well as the inner sunroof ...

In an era where BMW seems to be pushing the design envelope even further, the E30 is the literal definition of a simple “three-box” design. It represents a key pillar of the Bavarian brand.

In 1988, the BMW M division unveiled the M3 Sport Evolution. It came with a revised 2.5-liter version of the original inline-four with 238 horsepower, making it the most potent E30 M3.

While the BMW M3 typically has a six-cylinder engine, one particular version the E30, had a four-cylinder instead. Don't assume that means it's weak, though.
