We generally regard the Jaguar XJR to have been ushered in with the retro-styled X300 model. And that was indeed the first full production model to bear the XJR designation. It was also the first road-going Jag to employ a supercharger. But it wasn’t actually the first XJR; this was.

Before the X300 arrived in 1994, Jaguar and Tom Walkinshaw Racing (TWR) collaborated on this very limited-production performance sedan, of which only 425 examples are known to have been made. And this one’s up for grabs.

Based on the earlier XJ40, the JaguarSport XJR stemmed out of the same partnership that yielded the XJR-15 and XJ220 supercars.

The sedan debuted in 1988 with a 3.6-liter inline-six, but was later upgraded with a larger 4.0-liter unit – still naturally aspirated with six cylinders, but tuned by TWR to produce 250 horsepower. (The BMW M5 of the same era packed a 3.5-liter straight-six, initially rated at 311 hp.)

That was said to be enough to send it scampering to 62 mph (100 km/h) in 6.6 seconds. It also featured a fiberglass body kit, Speeedline alloys, a Momo steering wheel, and other performance and cosmetic enhancements to make it stand out from “lesser” XJs.

According to the listing, the price tag on this 1993 example listed for sale in the Netherlands was €98,216. If you adjust for inflation, that equals to €155,640 euros (or about $192k in US dollars) today.

These days a Jaguar XJR 575 starts at €143,900 in Germany (where this vehicle was originally purchased) or $122,400 in the US. Given that the XJ has grown considerably in size and position over the past couple of decades, though, the XF that slotted in underneath it might be a more relevant comparison.

Jaguar’s yet to do a new XFR (or XF SVR), but the top-of-the-line XF S with its 3.0-liter supercharged V6 retails for €71.160,00 in Germany, or $66,865 in the US, while the old XF R started at €92,700/$84,545.

However you wrap your head around the original asking price, though, it won’t cost you nearly that much today. This example has certainly been driven a lot, as it shows 270,000 km (167,770 miles) on the odometer. Valued at around $12,000, it’s currently up for auction on CataWiki, where bidding (at the time of writing) stands at $3,942, with nine days left to go.

The good news is that if you’re really interested but don’t want to enter a bidding war, it’s also listed on JamesEdition with a buy-it-now price of € 7,001, or approximately $8,600.
