1996 Jaguar XJS 4.0-Litre Celebration

The Jaguar XJS 4.0 (1991-1996) used the AJ16 straight-six with 249hp. More economical alternative to V12 with similar refinement. Final XJS six-cylinder. Values from £12k.

Engine: V12 - generally reliable but complex carburettors (some converted to EFI), cooling critical, distributor issues. 6.0 most reliable. AJ16 six - timing chain tensioner critical, head gasket. Transmission: GM400 auto (V12) or Getrag manual (six). ZF on late cars. Electrics: Complex - cruise, A/C, sunroof all problematic. Body: Rust in sills, rear arches, screen surrounds. Convertible mechanism complex. Budget £5-8k (six), £8-12k (V12) annually.
