Is my jaguar totalled?

I was driving from Miami up to Panama City Beach to see family and stuff when I stopped for gas just outside of Miami. I pulled up to the pump and rolled down my window to push the call for attendant button. I then waited for the attendant to arrive, and ran my credit card and stuff on the pump, and said, "filler up", but the attendant didnt seem too happy with me. I had them check the oil and fluids and such, and they said I was low on fluid in the transmission. I said I dont ever open the hood of my car, (I'm a model not any kind of mechanic or engineer, and dont want to damage the engine by messng with it), hence I dont ever check fluids, I usually take it in to service at the jag dealership but thats it. I asked them to add fluid, and they said that my car took K9P Transmission Fluid. He said he could charge it to my credit card, and he then brought out 2 clear bottles full of transparent cloudy yellow liquid, and poured it into my car transmission. and then added some brownish liquid from a bottle that said Mobile 1 on it. I then pulled out and headed out across highway 41 and towards the gulf coast of florida.

I then began to notice the automatic transmission making strange noises and slipping gears about a half hour down the road, and then the car lost some of its oomph, and it had to be floored just to keep going 30 MPH. The big guage next to the speedometer then was running way higher than normal (whatever that means, does that mean the car is working harder or something), and the little guage with the C and the H soon rose to the top H.

Eventually in the middle of the everglades the car just stalled out, and the engine wouldnt start, and spouted off all sorts of steam. I let it cool and started it back up and continued driving, and had several more stall outs, and eventually the car sopped putting off steam, but still stalled out. I thought I would limp the car to the gulf coast where I could get it checked, but the engine then started making all sorts of strange squeeking and rubbing and clanking sounds, and then suddenly BANG, a deafening sound rocked the car, and I lost all horsepower and then the engine stopped, and I coasted to a halt on the roadside in the middle of the everglades. THe car spouted off all sorts of smoke, and flames tore through the engine compartment. after the blaze died down, I looked under the hood and saw that there was a huge gaping hole in the engine, and some sort of weird black goop all over the place smoldering, and the wires insulation was just melted, and a lot of plastic was deformed.

I called a tow company to get an estimate, and they said it would cost $200 to tow, and that seemed steep. I would prefer to just keep limping my car to the gulfcoast to the jag dealership there so I could get a cheap fix to hold me until I can afford more expensive repairs, as the tow company said repairs would cost atens of thousands. Should I just call for a friend to rescue me, and leave the car on the roadside until the big payday in spring fashion season. Its not like I cant afford the repair, I make about $175,000 per year and can afford a JAG and a Land Rover. but i dont want to spend much before my bigger paydays to help conserve my savings.

People stopped and offered help, and said they could help me call a scrap yard, and that the car was a "total loss", someone even said that dumb models shouldnt be driving expensive cars if they dont know how to take car of them. That stupid guy said I should learn about cars before I continued driving a luxury car, or get some clunker. Why were they so rude. and didnt suggest a cheap makeshift fix?

Could the station have put in the wrong fluid , or what could have caused the problems and what would be the cheapest option for now, should I just get back to miami and take the land rover to panama city beach. What happened and what could I do?
