Hi, I’ve recently acquired a 2003 Jaguar S-Type R. Sort of rare. It’s the supercharged V8 model. The car is in good condition, but has 140,000 miles and needs some TLC, to say the least. I’m having trouble finding parts. Salvage yards tell me they have parts, only the donor cars are standard S-Types. I’ve been on Jag forums and found help with engine, supercharger, and mechanical parts.

I need the lower (under engine, trans) body panels from the front valance back through the trans including inner fender wells and spoiler. The correct parts have cooling channels for brakes and trans. Jag dealers want small fortune. I’m trying to get salvaged parts. I even bought all new aftermarket pieces from eBay UK. Struggled installing them, five hours on my lift, altering parts to fit. So, obviously not correct, as a “Jag expert” assured me. During my first test trip I saw my new panels in my rear-view, bouncing off the highway into a million pieces.

So, I’m looking for some direction in finding R Model parts. Any help would be greatly appreciated.

Sajeev answers:

The first step in finding cheap NOS parts (i.e. cheaper than whatever the dealer says) is acquiring factory part numbers. Maybe one Jaguar dealer will cough them up for you.  After researching via a online Jag parts vendor, it seems like everything starts with “XR8”. Which is a start, albeit not a great one. 

Pop that number into eBay and lots of cool bits for your Jag show up.  For an S-Type R grille, XR847243XXX turns into supercharged feline gold! And that’s a nice price compared to others I see online (well over $500). So get your part numbers (complete and partial) and make them all into saved searches, formatted by newest first.  Search these saved links on a daily basis — I often do this during lunch breaks.

This works. eBay works. I couldn’t restore my six undesirable Ford/Lincoln/Mercury vehicles (i.e. no dedicated aftermarket support like Mustangs and trucks) on an ongoing basis without it.

From there, plug your part numbers on Facebook PagesRear Counter, Car Part, LKQ and do business directly with the vendors you meet on eBay. They often drop a business card in the shipping materials. You never know, you might find a Jag dealer looking to dump their old inventory quickly! Sometimes all it takes is a business card, a phone call, and a part number to get what you need.

    Lots of junkyards do not list things like under-engine covers but I have had good look finding parts by searching nearby parts on The other advantage of searching this way is that bigger parts are differentiated by trim. For your lower covers, the best way to search would be to look for a front bumper assembly for the S-Type since those will be tagged with standard and R. This will give you a list of the junkyards that have a front bumper for the R and will likely have the lower covers too once called.

      Bozi has a good idea finding the car is a good place to start. I used to search for the engine for my H6 Subaru then call the yard to see what other parts they had. Back when I worked on my 4×4’s on a daily basis I made friends with the parts guy at the local Mopar dealer. He was great about sharing diagrams etc with me. Just don’t bother them when their crazy busy.

    Keith (OP) Good luck on your thankless labor of love. As with all projects of this nature it will never be sellable for what you have in it but that’s what marks you as an enthusiast.

    You bought a used Jag, and a rare one at that. Get used to ponying up at the dealer or pull the pin. This is how luxury brands keep poor people from being seen in their wares.

    Another vote for Car

    I did a minor restoration of an IS300 SportCross. Finding part for that was sometimes a challenge. For specific items I wound up getting them from eBay. But for large parts and more common parts (like seats and trim that were the same for the sedan and wagon) I found Car Part was great.

    Do not email the yards. I never once got a reply. But without exception, each and every yard I called treated me great. Some places went WAY out of their way to help me. Several were willing to take and text me photos of the parts. Many warned me that the parts were rough. I never went to get some parts and walked away empty handed or disappointed.

    When you back yourself into a corner with a really uncommon car, you’re going to run into issues finding parts. But like Sajeev said, sometimes you can stumble upon a shop that stocked up on parts for unpopular cars that are collecting dust in the warehouse.

    Sounds like a good opportunity to get experienced with making one-off composite parts.

    It’s easier and less expensive than most people think it is.

    When it comes to Jags, getting the part number is fairly easy. You can download the Jaguar Electronic Parts Catalogue here:

    It’s a bit of an ordeal to install it but fairly easy to use once you do.

    The cheapest place I’ve found to get genuine parts is Jaguar Land Rover Reno Parts:

    Terry’s Jaguar parts ( is also good.

    Welsh Enterprises ( has good aftermarket prices and a substantial salvage yard.

    Jaguar Specialties offers kits for to swap in an LS motor.

    Another good source for parts and info is your local Jag car club.

    A third for Your best bet IMO is to use the techniques described, or to search for the supercharged motor only, in order to find a yard who has or at one point had a donor car. More often than not, the medium to smaller yards will have the whole car.

    I would appreciate reading your driving impressions of this car, once it’s sorted. I’ve had a similar vintage XJR on my shortlist for some time but haven’t previously thought about one of these.

    I’m new to TTAC, didn’t realize you were a contributor. I have enjoyed your contributions to Y U RUNE KLASSIK.

      The XJR is a much better car, and was much better sorted in 2003 than the S-Type Ford Lincoln LS Thunderbird sedan. Of course that was the final year before the restyling and use of aluminum for the 2004 XJ.

    Love is not practical.

    LS swap sounds fun

    Just buy the best S-Type R in the US. It will cost you far less than fixing the one you’ve got.
