Hey guys, im looking for advice please. Ive been wanting one of these for a while and this has just popped up (link below), it looks great but is the milage 291KM a dealbreaker? Any advice is much appreciated.

A car with low mileage MAY be caused by being in the shop for months at a time, too troublesome to drive, not reliable enough to drive any long distance, or up on blocks. MAYBE.

180k miles isn't unrealistic as long as everything runs and operates fine. LOTS of required maintenance during those kilometers though, they should all have been done at least twice:
ALL fluids
Suspension bushes and such replaced
Paint protection or maintenance of some sort
Interior care
Possibly catalytic converters? Those are a fickle item.

 

JohnM: I'm fine with buying a X150 with up to, say, 70K miles -- but only if I have complete maintenance records. As these age, there a list of things that will wear out over time, and wear out faster when you add mileage. At 180K, it's even more important to see what's been replaced.

Also, I'm a pretty good shadetree mechanic, so I can do 95% of repairs that start appearing around 70K and up. Also, I can find lots of alternatives to Jag-branded sources for parts, at reasonable prices. I never take my cars to a mechanic. Point is not to seem to brag, it's to point out that repairs on any car are really expensive, and Jags more so.

So I wouldn't recommend buying a high mileage X150 unless you know exactly what's been done, can DIY most repairs and source reliable OEM parts. Or have a bank account that might be better spent on a lower mileage X150.

YMMV.

 

Indeed, significantly too low a mileage for the year can be worse in many cases. Machines don't do too well when they are left to sit. Corrosion forms on surfaces once all the oil, fuel or coolant trickles down off them. Organic materials like plastics, rubbers and vinyls break down over time more so than mileage and in the case of engine seals and gaskets, they deteriorate faster if they are not kept bathed in oil. What tends to happen to result in low mileage is somebody racks up most of the mileage when the car is new, then something happens (either to the owner or the car itself) to cause it to be put away in storage (or usually just left wherever it was rather than stored properly). I've done it myself, bought an amazingly low mileage car only to have it spring a leak from literally everywhere upon starting to drive it again. I've known a lot of collectors to buy cars out of long-term storage and this is typical.

Most of the "high mileage" cars that I've been aware of tho racked up most of their mileage during the first few years by very active drivers. My sister used to get a 2-year-old Buick every few years from her father-in-law who was a traveling salesman. He'd typically rack up 150K to 200K miles in two years, buy it cheap off lease to give to one of his kids or grandkids and his company would lease him a new one. But then she'd get another 100K relatively trouble-free miles out of it over the next five years. So this Jaguar could still have been in storage for an extended period of time.

If the mileage was accumulated at a fairly steady rate over the whole time, regularly maintained and repairs made as necessary, then it could be a great car. Just remember the used Jaguar motto "No records = No Sale!"

 

I have 220,000 miles on my XKR now. And now there are some issues that I need to address, but for the most part it has been an extremely reliable, wonderful car to own. The key to buying a high mileage car for me would be a service history that showed documented oil changes at more frequent intervals than the factory suggests. Mine is changed every 3000-5000 miles. Also with the transmission, I've never had an auto go a 100,000 miles without needing work let alone 200,000. I have the fluid changed about every 65-70,000 miles, and it's still good. My car has not been babied, it's been tracked many dozens of times. So, as Cee Jay alluded, the fact that a car has that much mileage means it was capable of doing it without too much issue. But verifiable regular maintenance history is a must if you're going to expect some longevity.

 

220K miles most impressive!

The question of "too much mileage" is answered by a personal choice.
The real question is, are you up for the maintenance of such a vehicle.
