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.

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 Pages, Rear 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.

  • Zerofoo "Hyundais just got better and better during the 1990s, though, and memories of those shoddy Excels faded."Never. A friend had an early 90s Hyundai Excel as his college beater. One day he decided that the last tank of gas he bought was worth more than the car. He drove it to empty and then he and his fraternity brothers pushed it into the woods and left it there.
  • Kwik_Shift There are no new Renegades for sale within my geographic circle of up to 85 kms. Looks like the artificial shortage game. They bring one in, 10 buyers line up for it, $10,000 over MSRP. Yeah. Like with a lot of new cars.
  • Ribbedroof In Oklahoma, no less!
  • Ribbedroof Have one in the shop for minor front collision repairs right now,I've seen more of these in the comments than in the 30 years I've been in collision repair.
  • Tassos And all 3 were ordered by Fisker's mother. Seriously, given Fisker's terrible record of Failure in the past, only an utter loser, (for example, VGhost or Art Vandelay?), looking for a BEV terrible enough to be a proper replacement of his 11 mile range Fiat 500E, would order one of these. (apart from Fisker's mother)
