We bought this car in May from a dealer who advertised it as "mechanically great - no work to be done, ready to drive". That should have been a red flag right there. But it wasn't a fixer-upper.
This review is in October - 5 months later.
(First Mechanic's Service)
Brake calipers had to be adjusted.
Opened up windscreen washer jets on the bonnet - they were clogged.
Replaced fuel injector hoses (that's why these things toast marshmallows from time to time - replace them if you don't want a bonfire).
Sonic clean of injectors.
Smelled remarkably like old caravan at first. Turned out the air conditioning pipe was blocked, and water had backed up and saturated the underlay for the carpets. Carpets easily removed and dried out; mechanic unblocked tube. No more problems.
(First Service: $1400)
(First Electrician visit)
Headlights went off sporadically over speed bumps. The Prince of Darkness (Lucas) was strong in this one. Electrician wired around the fusebox and fixed this.
Air conditioning regassed. Put in an override under the dash so it turned off properly.
Replaced air-con switch on the front panel - micro switches had had it.
Horn worked once. Apparently the steering columns collapse over time - only slightly - but this stops the horn working. Electrician put in override.
Heater assembly reviewed, revised and corrected.
Cooling fan thermostat went - cooling fan wouldn't turn off. Electrician replaced thermostat.
(First Electrician visit: $1900)
(Second Mechanic's visit)
Glass in passenger door slipped off rails when frustrations with Jag boiled over in slammed doors :).
Handbrake adjusted - apparently they're 'holding' brakes, not a 'park' brake; you shouldn't use them unless the hill's really steep.
Replaced thermostat in engine - had wrong thermostat fitted that wouldn't let it reach operating temperature, with subsequent "absolutely horrible" fuel economy. Would sit at 60 degrees rather than 90.
(Second Mechanic's visit:$400)
Replaced antenna drive motor - old one had given up the ghost.
End trim was missing on end of dash ($10).
Replaced indicator light assembly in the rear bumper - old one had had screw holes stripped and the lens fell out on the highway (only $10, but took a couple of hours to fit with my elite skills).
Radio (old cassette player, must have been in since the early 90s) replaced with a cheapie radio.
Digital radio replaced the cheapie radio when we decided we were keeping the Jag (oh boy).
Switch to operate passenger window died - got a replacement easily enough ($5 per switch).
(Spares purchased: $600)
(Third Mechanic visit)
This was the OMFG visit (what, the others weren't?). Car was running rough on idle. Not good over speed bumps. Handbrake (ha!) gone again. Coolant leak. I'll note we received an estimate of $4,000 to do this work. Estimates don't mean much in Jag-world.
Power steering rack replaced.
All six shock absorbers replaced.
While it's up on the hoist, you may as well re-do the brakes - normally a $1300 job. So that was done.
Handbrake fixed - but instructed not to use it. Ever.
Cleaned fuel lines and drained fuel tanks. Got rid of all the sludge in the bottom of the bank. Apparently never cleaned in 26 years - there are drain hole covers that hadn't been touched.
Cleaned drain holes near fuel caps - water possibly seeping in through the fuel cap, as it couldn't get away through the drain holes.
Replaced ball joints. All ball joints.
Fuel sender unit for one tank was replaced. One of the tanks wouldn't tell you how much it had left in it.
All bushes, various rubbery parts and seals (leaking from brakes, coolant, power steering fluid, transmission) replaced. This car had apparently been let sit since an engine rebuild 5 years ago - these cars need to be run and keep lubricants up to those rubbery bits.
Basically the suspension is completely brand new now. I had expected to have to do this at some point; on the plus side it now goes well over speed bumps, and suspension is just great.
Lots of other little things I've probably forgotten.
(Third Mechanic visit: $5963)
(Fourth mechanic visit)
Car 'squeaky' now after suspension rebuild. Probably new rubbery bits needing lubrication.
Four days after picking up the Jag from the OMFG mechanic's visit, the Jag broke down on one of our busier roads. Wouldn't fire over; still running rough and idling badly. Ended up getting it flat-bedded to the mechanic.
The wife's commentary to the mechanic was, I am sure, enough to make a sailor blush (recall that this was the reason we put it in on mechanic's visit #3 to get fixed - not suspension!).
(Fourth mechanic visit: $who knows)
