WTF?

That made no sense at all.

It makes perfect sense. Energy is being wasted in the system.

By power I don't mean 0-60. I mean total energy put in to the wheels.

But thats not really whats going on here. It takes a LOT more energy to move a car than to freewheel a gear. If he puts his AWD back on, he's not going to half his mileage, and he's not going to get 50% of his power back.

I bought a Ford, I expected it to work, it works fine - better than your Honda or Toyota or whatever, I suspect - 30k miles, 6 oil changes, and 9 months later and the only noticeable difference is that the whole front end is covered in little tiny paint chips, but that's because Pennsylvania doesn't care about gravel buildup on interstate highways, and all the improperly applied wheel balance weights the stealership put on fell off - total cost of that repair was $44, and had nothing to do with Ford at all, but instead a crappy 15-minute dealer detail and prep job right before closing time.

I fully accept that he's an idiot. He went to Dover High School in Dover, PA. Creationism, anybody? He also believes every 9/11 conspiracy theory (you know, nukes, months of clandestine weapons installation, remote controlled airplanes, killing fields and concentration camps for airline passengers) and becomes violent whenever someone tries to engage him in intelligent debate about it. Most people I know from Dover believe that crap. They also tend to have abnormally high levels of sexism and racism, and immediately categorize any women as sluts, blacks as lazy and violent, hispanics as lawnmowers who can't speak english, and middle easterners as terrorists (which I find especially amusing, given the "9/11 wasn't terrorism" viewpoint). Dover actually taught no hard sciences - physics was optional and never ran due to low enrollment, biology had all kinds of crazy religious stuff built in, computer science was a joke ("We never actually programmed in Comp Sci 4, we just paid off the teacher with diet coke and candy, and played Halo all day"). To be honest, I know people who were homeschooled who came out less socially dysfunctional, and I know people who came out of terribly funded inner-city schools with more well-rounded educations.

Oh, and since the whole Intelligent Design ****** hit the fan, Dover hasn't really improved. They reworded things a bit, put up an enormous chain link fence, and nobody's allowed outside anymore. Same ****** still happens inside, and they want to keep the reporters at a distance.
So yes, he's an idiot.

Tempo prices around here seem to be artificially inflated, they're all in the $1-3k range, because there appears to be a demand for them (I see them on the road ALL THE TIME, I can't explain it. Half my neighborhood drives Tempos. The other half drives Probes. I blame Three Mile Island.)

Whoa, the Tempo is a total econobox, but at least it's SOMEWHAT reliable. The Probe is a sh!tbox. And $6000 for a 1990 Tempo? PLEASE tell me you're joking...

IMHO, if you have any mechanical aptitude at all, you NEVER buy used cars at a dealer. If you don't have any mechanical aptitude at all, you find a friend who does, and STILL never buy used cars at a dealer.

Exactly. No one yanks the halfshafts for no good reason; it's kind of a pain.

Unless, of course, they were working on the car, put it back together, and then realized they forgot to install them, but decided it wasn't worth taking it back apart and doing it right:laugh: Which indicated a degree of incompetence that would make me run screaming.

So he still has $4800 left from the insurance settlement? Tell him to go buy a real car. My MR2 is ten times that car that Tempo will EVER be, and it only cost me $2100. Just get him a Corolla or something if he just wants a boring econobox...

He doesn't have $4800 left - where do you think the money for his sudden 10-day "Ima lose my virginity" trip came from?

And considering the whole car looks to be rebuilt (why?), I wouldn't be surprised if incompetance is indeed the reason for the missing drivetrain components. It's certainly the reason for the turn signals not working at spec.

And on dealerships... Buying at a REAL used car dealership, where the cars are newer than a quarter century is passable, if you have a keen eye and their volume is high enough for them not to need to rape you to the tune of a couple grand to pay for their kid's next meal.

But buying at a shady, small, run-down shack car dealership that sells approximately 1 car a month, if that, is quite a different matter, and that's what we're dealing with.

put the halfshafts back in if itll even work. Installing halfshafts in my exprience are not hard things to do. I had to remove and install 2 halfshafts on an AWD 91 civic and it took me 1 hour and most of the time was spent searching up how to not fvck up too much on alldata. I'm thinking the reason they are not in there is less laziness and incompetentence since tis so relative simple and quick to do but a larger mechanical problem.

Yuo also might want to get your arse away from 3 mile island. In the sane parts of america(aka anywhare not near 3 mile), probes are incredibly rare and I havent seen a tempo in months. BTW, I work at a major ford dealership so I probably see 20x more fords than the average person every day.

You said "twice the power = twice the mileage"

Again, that makes no sense. Why would you get twice the mileage if you put out twice the power?

I bought a GM (Chevrolet), not some honda or toyota or ford for that matter. It gets better gas mileage and better tire wear than all of the above. 30k miles, original factory tires, breaks, and yes, ive had to put a windshield in it because of the gravel.
The problem with pennsylvania's roads isnt because they dont care about gravel buildup on their interstates. Its because their too cheap (and too environmentally challeneged) to use pure salt during winter season. So they use a mixture of 50% salt, 50% gravel (yes, they actually spread fvcking gravel on the road) as a melt/antiskid for winter spreading. Blame your dam governer (Rendell, AKA cheapass jewboy) for cutting the PENNDOT budget and workforce so he can grease the teachers union and school spending and those who are trying to help him get slots. (Nothing like a 3 year wage freeze for state workers, while you, your body guard patrol, and your sens & reps take pay increases and eat filet mignons at dinners, while you screw the rest of the state workforce.)
This is why governors of PA should never be allowed to come from east of state college. Everyone solves the problems of harris-delphia, while screwing pittsburgh, rural sw & central pa, and erie.
