Frequently Asked Questions

Is an older Mercedes 320 safe?

The 12 reported deaths associated with 320 models warrant serious consideration. These vehicles lack modern safety features like stability control, side airbags, and advanced crumple zones. While solid for their era, they cannot match current safety standards.

What is the biodegradable wiring harness issue?

Mercedes used environmentally-conscious wiring insulation in the 1990s that degrades over time, causing electrical failures. Symptoms include intermittent electrical problems, no-start conditions, and warning lights. Replacement harnesses are available but expensive to install.

Are 1990s Mercedes expensive to maintain?

Yes, increasingly so. Parts become harder to source, and finding mechanics familiar with these systems grows more difficult. Budget significantly for maintenance, and avoid these as daily drivers unless you have mechanical knowledge or a trusted specialist.
