Driver seat belt warning light, a singleton red warning light right on top of the facia. Irritating, but easily overcome by unplugging the wire socket at the belt buckle anchor.
A blown fuse for the facia lights - original 5A fuse lasted 16yr!
Too early to give feedback on other bits.
It is quite simply a beautifully stunning car, drawing crowds of admirers everywhere! I prefer to cruise along at a sedate speed which belies its 250bhp - this is a car to be seen in, not to be seen as a blur.
I found the clutch and brake pedals surprisingly heavy for a luxury car like this - constant use in urban traffic can become tiresome. Or it can build me thick legs!
The steering seems to have a tendency to over steer, but holds itself steady enough during harsh cornering, with no hint of lifting off the road (it's too heavy for that as well).
The straight 6 AJ6 engine is sweet and a good runner, however even the gas pedal started to feel heavy after a time on the motorway. I feel it is best on the motorway where you maintain a constant speed - fuel consumption then becomes a respectable ~30mpg. Otherwise urban + countryside steady driving (no gunning or thrashing) returns some 25mpg.
Over 2000miles it's returned 27.7mpg, which includes some spirited driving through north Wales. This is surprisingly good, but I did put in STP oil additive (to clean the engine up) as well as fuel injector cleaner to the fuel to enhance the old car (there must have been lots of cack in the engine over its 102kmiles because fuel economy improved from 26.4mpg to the above 27.7mpg.
The faulty instrument panel lighting problem was traced to a broken line on the printed circuit ribbon on the back of the panel, which the dealer rectified (Swallows Jaguar are well recommended - Gary Robinson and his crew are very friendly, helpful and honest chaps). Also check the cigar lighter wiring under the central console - see that the wires do not touch the chassis bolt nearby otherwise that could short out.
I'm still loving it!! It's made motoring so pleasurable.
