If it is equipped with an air conditioner,probable cause would be the a/c cooling coil drain pipe may have come loose or clogged, thus making the condensed water from the cooling coil to spill over on the carpet. Have a look under the box that holds the cooling coil, there should be a drain pipe that goes through the floor towards the front.

Consider the lamps of both models will be switched by a computer that will probably be monitoring the current consumption. Led lamps consume less current and are polarity sensitive. The most important thing about such an upgrade is not so much discovering how to wire the lights but discovering how not to wire them. I suggest you obtain a wiring diagram for both models to discover whether the new lamps will be compatible with the existing wiring.

i really doubt it is the rack and pinion. I will not work on Euro cars but work on American and Asian cars frequently. Check tire pressures first. There is usually a sticker in the driver door jamb in the US that tells the psi recommended for tire pressures. Then try to drive another similar one at a used car lot. if ok then jack up car and put jack stands under it and lower onto the stands or bring to a professional that knows how to be safe as this is dangerous. The ball joints and strut mounts need to be able to turn smoothly. If alignment is off then the steering wheel will not return properly. That can be a caster problem from a bent control arm or strut or misadjustment.

Leaking or missing vacuum lines can definitely make an engine die or run poorly. In my experience, once you've unhooked an old, hard rubber line, it probably won't seal properly when you hook it up again. So I suggest changing all the lines that you can reach. Also, there's usually a big vacuum line to the power brake booster, which can leak a LOT of air if it gets hard and doesn't seal properly. The cruise control motor, which is vacuum operated, is another place to check. Also, check the vacuum line(s) to the PCV valve and the rubber seal that it sits in -- again, a likely source of leaks. Any idea why the previous owner disconnected some of the lines? If he was trying to solve a problem, it may still be there when you replace the lines, and had nothing to do with them.

That is ok. Jump the battery and let the alarm sound while you open the trunk

It's not unusual for a thermostat housing to get stuck in place. Try tapping it sideways with a hammer (gently) from different positions to loosen the bond, or stick a screwdriver in a bolt hole and see if you can lever it off (again, gently). Plan B would be to get a sharp utility knife and try to work it into the gap between the housing and the engine. IMPORTANT NOTE: Be sure to remove ALL old gasket, sealant, etc., from the mating surfaces before installing the new gasket. Otherwise, it will leak. Don't use a sharp object like a screwdriver, because any gouges will cause leaks -- try a putty knife, plastic scraper, stiff brush, specialized gasket scraping tool or nasty chemical (gasket remover, mineral spirits, lacquer thinner, etc.)

Call a jaguar dealer.

Not sure about the horse power, but the Jag V12 has a capacity of 5.3 litres

It just pulls up. It's held down on four push fit connectors, one in each corner

Where the top radiator hose goes to the engine, under that flange that is bolted to the intake that the top hose is hooked to is where you'll find said thermostat. Drain the coolant before removing those bolts to replace it. Clean everything well and put a new gasket on, put the goose neck casting back in place and tighten the bolts. Replace the coolant and done.
