    Xjr 4.2 supercharged model, how often do they come up for sale? Lpg?

    Hi guys,
    My background is classic bmw's, I'm not a mechanic by trade but used to getting my hands dirty.

    im currently restoring a straight 6 3.2l e36 BMW m3.

    i keep reading about the NA 4.0 xk8 and the 4.2 supercharged. I do big mileage each year so petrol costs would be sore on me. I can imagine the thought of lpg would be sacrilegious to many enthusiasts on here and I'd feel the same when it comes to BMW m3's.

    i spend a lot of time in traffic in the city so an auto is very appealing, I'm used to 300bhp+ car so the v8 xj is again very appealing.

    how often do they pop up for sale? Is many on here driving a lpg'ed 4.2 or seen many come up for sale already converted?

    thanks

    The occasional one comes and goes, the key is to keep your eyes peeled

    We had a P38 range rover, blew it's Becm up anywhoo .

    The system on that engine needs servicing regularly, the company that installed it recommended it be serviced every 12 months, fuel filter injectors etc etc so that's a consideration.

    so my advice would be to find one with a relatively new conversion, also the LPG sysytem should be a quality system I:E BRC..

    They are relatively high maintenance compared to standard however the fuel savings are quite substantial.

    57p per ltr for gas compared to 122p for petrol.
    Thats the prices around my neck of the woods.

    if you can't fix it with a hammer, you've got an electrical problem.

    They also do 4.0 supercharged v8 from 1997.

    Xj is 4 door
    Xk is 2 door.

    Ok cool,
    What would be a good price to pay for an xjr with average miles?

    Are there any comprehensive buying guides?

    thanks

    XK8 is NA 4.0 to 2003 then 4.2 to 2006 when the X100 was replaced by the X150 XK
    XKR Launched 1996 4.0 Supercharged to 2003 then 4.2
    X308 (this forum) was 4.0 XJR or 4.0 NA XJ8 the 4.2 engine is only available on the X350 Aluminium XJ
    LPG conversion is achieveable but not common.

    The aluminium ones or lighter (more mpg) and more rear leg room.

    There was a BG to the XJ8 in a recent Jaguar World magazine. You could probably get a back issue. I've never seen anything comprehensive that's specific to the XJR/XKR, though. But then, there wouldn't really need to be, since the only essential differences are the supercharger element, uprated brakes and so on.
