633CSi (1976-1984)

Can you afford a 1976-1984 BMW 6 Series 633CSi in 2025?

# 1976-1984 BMW 633CSi The BMW 633CSi epitomized 1970s grand touring elegance with its shark-nosed styling by Marcello Gandini and Paul Bracq. Powered by BMW's silky 3.2-liter inline-six producing 177-197 hp (depending on market), it delivered refined performance rather than outright speed. Enthusiasts praise its graceful handling balance, sumptuous interior, and timeless pillarless coupe design. However, it's notorious for complex Bosch fuel injection issues, deteriorating wiring harnesses, and rust in shock towers and floor pans. Reviews highlight its comfortable long-distance cruising ability and mechanical sophistication, though some criticize its dated performance by modern standards. **Best suited for:** Classic car enthusiasts seeking an elegant weekend driver with affordable entry costs compared to contemporary Porsches. Ideal for relaxed touring rather than spirited driving. Requires mechanical knowledge or a trusted specialist for maintenance.

The 633CSi requires frequent valve adjustments, expensive Euro-specific parts, and complex Bosch fuel injection maintenance. Rust prevention is critical. Surprisingly, insurance is often reasonable due to classic car status. Fuel injection computers and period electronics are reliability concerns. Parts scarcity drives costs up. However, mechanical simplicity compared to modern BMWs means skilled independent shops can service them affordably.
