Hi everyone

I m considering purchasing a 1993 XJRS coupe /
The car is in excellent condition very well-maintained black and has 50,000 miles


one owner with all records - black on black
here is the question
How much do you think it’s truly worth in today’s market?

I already own a 1994 XJS v12 Coupe in pristine condition with 11127 original miles on it therefore I’m considering selling mine to purchase the 93XJRS how do you feel about that? Am I making a mistake

thank you

 

I would say, mistake!
XJRS ignition parts are unobtainable, and it will be n faster than the car you have.

 

Greg,
He's not buying the car to drive it. If the 96 has 11,000 miles on it, I think he intends to buy this car as an investment?

 

Terry,

Facelift XJR-Ss will always be super-collectable and rare! Buy it! Lovely cars!

As mentioned the problem is if something goes wrong with the fuel ECU. The Zytek system is basically unservicqble now, as there is no technical support or the ability to read codes ( at least as far as I know).

The Jag mechanic I sometimes use was factory trained and spent about 20 years at the dealer before setting up his own shop and he had one of those cars in that wasn't running right. He was asking me for advice, as he could find absolutely nothing about the fuel system and it was throwing error codes - so proceed with caution!

 

Only way to buy one of these things if you plan to run it seriously is to do so on the understanding that either you are setting up for a serious learning curve (that is assuming that you can get a cable and software to read the existing ECU - and I've never seen one of these for sale and Zytek won't sell you one) or the existing fuelling and ignition system have to go because the distributor is all part of the package. Story goes that most Jaguar dealerships had no clue about these things and spoke to Jaguar Motorsport to sort issues.

There's quite a bit of information here >> XJR-S - Zytek approx halfway down the page.

Replacing the whole thing either entails switching in a standard 6.0 set up or otherwise entails a bucket load of research, something like Megasquirt and I'm not doubting a fair bit of trial and error, particularly on fuel maps, most of those able to read the factory units won't share the information even assuming you could find somebody. All this whilst understanding that getting the mixture wrong will convert the engine into a boat anchor very very quickly if you input any enthusiastic zeal - the standard V12's are prone to this also so I've no reason to think that these aren't.

Then there is the purist approach that should you remove the Zytek stuff 'Originality once lost cannot be recovered' and it is no longer an XJR-S but I'll let others debate that one.

For the very same reason I don't really want an XJS newer than 87 I'd treat an XJR-S to a wide berth - technology that is immature and in some cases unobtanium. If it is for investment only then I'm not sure this would be a wise choice either - consider a good Le-Mans limited edition instead - it is the one XJS that I had a chance to buy for less than 4k - I kick myself every time I see where their values are now -

 

It's admittedly much easier in the UK with a number of specialists that understand the Zytek system and also the ability to replace it if absolutely necessary. Also the fact that XJ220s and XJR15s are understood and supported over here with the Zytek system.

I certainly wouldn't hesitate at all about buying an XJR-S in the UK, but accept that it may be a different issue overseas.

Youre better off buying a DB7

 

No, he will be worse off!

 

So basically stay away from a pristine 1993 XJRS
But what would it it’s true value ?
remember pristine condition , one owner and 50k miles all service record-

 

The monetary value is whatever somebody wants to pay for it, the expectations in this area often exceed reality, as does the definition of pristine - I can find defects on new cars in the showroom ... much would depend on how long you are prepared to hold onto the car and how long you hold out for the price you want. A very good indicator is the 'sold' listings on E-Bay although you may not be able to find the exact same value. There's a car in the UK that was the subject of a 75k restoration and it has been for sale for half that price for months if not a year or more. These are simply not an investment car unless you plan to keep for 10 or more years I think. As it stands it seems that you have a pretty nice example already.

With these cars such a low mileage to anyone that knows the cars is a warning - they do not respond well to sitting around, in fact no car does, so the value becomes subjective as I would actually temper my offer with that in mind if I planned to actually use the car. Lack of rust and such is great, appearance probably 10 out of 10 but if pressed into regular use so many unknowns.

Then there is the other kind of value that is not defined in monetary terms - this one is entirely subjective - I have a car that's the only one of its kind, I could probably realise 5k for it - but I wouldn't sell for 10 times that, I have another in my garage that even as a box of parts will fetch 2k+ but it has been in the family from new, since 1977 - again no amount of money would buy it.

If you like the car and want the car go for it but don't do so purely for financial gain there are better investments, buy it to enjoy - there's value in that.

 

Terry,

Late XJR-Ss are lovely cars and one of the most desirable XJSs.

If you like them and can afford it, Buy it....but at the right money, and with your eyes open.

Good luck

Paul

Out of curiosity,,,, what parts of the EFI system (if that's what folks are talking about) are un-obtain-able?

 

You will really struggle for pretty much most of the Zytek stuff - which is the ECU essentially - it was very specific to the Jaguar and isn't a generic Zytek system, the distributor components were also changed so they aren't standard either.

Even if you have the parts fault finding and remediation will be a massive struggle even here in the UK let alone the USA.

 

Thank you every one for those detailed responses . Much appreciated. I have decided to pass on the car not because i don’t think it’s a great investment or because of its ignition issue, but because I already own a few XJS with very low miles on them - 11227 and 12447 ( I think )

my 4 cts( inflation! Inflation) Aha

 

Pretty much all of it. The XJR-S was built by TWR Racing in a partnership with Jaguar at their factory in Bloxham, Oxfordshire, not the main Jaguar factory. It used a unique engine management system that wasn't used on other production Jaguars.

Edit to add: The 6.0 engine was a derivative of the engines used by TWR in their racing series, and is different from Jaguar's own later production 6.0.
