2004 Jaguar Xj8 problems
The Jaguar XJ (X308) is a full-size luxury saloon car manufactured and marketed by Jaguar Cars for years 1997–2003 across two generations and featuring the Jaguar AJ-V8 engine and Jaguar independent rear suspension. It was the third and final evolution of the Jaguar XJ40 platform that had been in production since 1986. It was preceded by the Jaguar XJ (X300).
Exterior
The X308 kept much of the same exterior styling as its predecessor, the Jaguar XJ (X300), carrying its rounded four-headlamp bonnet, low roofline, sloping tail, and wrap-around rear light clusters. From the front, the two generations can be differentiated by the shape of the indicator lenses (rectangular on the X300, oval on the X308), and also by the shape of the fog lamps and lower valance air intake, both of which are more rounded on the X308.
The front and rear bumpers were both changed along with the taillights which had red/clear lenses rather than red/grey lenses. The grille surround and badging was slightly changed. The headlight fixtures also included forward parking lights housed with the brights, new to X308.
