Exactly how much will an XJ12 hurt my wallet?

This one looks minty http://www.ebay.co.uk/itm/Jaguar-XJ-Series-6-0-aut...

But they're never going to get £12k for it.

This bit caught my eye.

has had a full £23,000 restoration in the last 3 years with all invoices to be seen

This is the first time I have heard of a full restoration on an X300, with the car priced accordingly. I wonder how the market will respond.

Hats off to the previous owner who had the restoration done. Taken at face value, he has rejuvenated a fantastic car, even though the sums don't stack up to do so. I hope he knew what he was undertaking.

'Chapeau', Sir.

JI know the V12 from the E type, XJS and earlier saloons to S111. It's an engine which is pleasant and smooth, but stifled by strombergs in an E, fitting stand alone management and tubular exhausts lets the power and the beautiful sound out- why did they make them sound like hoovers, same period Ferrari V12s don't ?? The XJS and saloon with pre and post HE factory engines ALL have shocking fuel consumption and disproportionately low power. I have a 1991 XJS V12 Le Mans, which is 5.3 but has the late block and cats, and it flies, and makes it into the twenties on fuel consumption, and the thing has proper oil seals too. Presumably the X300 V12 has this much much nicer engine? That and a nice six speed manual would fix it for me!!

They have plenty power, one high compression version of the V12 produced during the pre-HE/HE crossover period has more power than anything other than the 6.0litre. The fuel consumption and lethargic progress is largely teh gearbox and torque converters fault; if your Le Mans was fitted with the spin dryer that passes for a torque converter and the 3 speed auto it would have the same symptoms.

Changing the sound is also easy, just change the silencer boxes. They were designed to be quiet, that was part of the appeal of the engine especially in the SI - III XJ12, and why the cars also had ridiculous amounts of soundproofing and care taken to isolate the subframes using large rubber bushes. The exhaust manifolds themselves on the V12 are pretty good, they worked well for TWR and Group 44.

The X300 XJ12 with the 4 speed GM autobox is a bit of a revelation compared to the older versions with the 3 speed slush-o-matic. It still doesn't feel like 330bhp or whatever they claimed, but it also doesn't feel like about 170bhp like the earlier cars do! I never found it to be quite as smooth as the earlier engine in a Series 3 though. You'd have to have been a die hard V12 fan to get one over the supercharged XJ6 new I think.
