1988 Pontiac Grand Prix: Buy or Avoid?

The 1988 Pontiac Grand Prix, a classic W-body, offers a nostalgic blend of American styling and comfort, but its age demands a careful approach. While the optional 3.8L V6 is remarkably durable, expect to address common issues like aging electrical systems, suspension wear, and rust, typical of its era and platform. It's a car for the enthusiast or DIY-er willing to invest time, not for those seeking modern, trouble-free transportation.
