Driver Aids and Safety Features:

BMW 635 CSi Features

The BMW 635 CSi hails from an era where driver aids were minimal, and driving was a hands-on experience. While it doesn’t boast the electronic aids found in modern cars, it does have features that make it advanced for its time:

  • ABS Braking: The 635 CSi was equipped with an anti-lock braking system (ABS), a significant safety feature during the 80s, helping to prevent wheel lockup during challenging braking situations.

  • Rigid Construction: BMW’s focus on a wooden body structure meant better protection during a collision. The car’s solid build quality improved safety and enhanced the vehicle’s overall driving dynamics.

  • Passive Safety: The interior is designed with safety in mind, featuring a well-supported seating position, and for later models, airbags became standard, offering additional protection.

Modern Considerations:

It’s worth noting for potential buyers that Si has charm and mechanical purity, it lacks the comprehensive safety nets of traction control, stability control, and advanced airbag systems that are standard today.


Should You Buy a BMW 635 CSI in Today’s Market?

Owning a BMW 635 CSi today is about embracing the essence of classic motoring. Here’s why it might be a compelling buy:

  4. Mechanical Simplicity: Its relative mechanical simplicity compared to modern vehicles means that maintenance and repairs can often be more straightforward, assuming parts availability.

The M variant offers a more intense driving experience and a higher collector status, reflected in its price. The standard 635 CSi, while less potent, still provides much of the charm and driving enjoyment at a more accessible price point.
