comment Front, driver-side wheel sounds like it's skidding when braking
Let me rephrase: have you checked your tire pressures with a gauge? Do they match the recommended pressures for your car? There's a plate inside the drivers side door (in the US) that lists the correct pressures. They're also found in the owner's manual.

Are your tires fully inflated?

comment low speed vibration, not in the steering
Is the vibration independent of the speed of the car? Is the vibration tied to the rpms of the engine?

comment Improving fuel economy in high-milage automatic transmission car
This question is a bit vague as written: you've left yourself open to the standard answer of "it's the driver, not the vehicle." Here are some suggested additions: What specific vehicle are you talking about? What are some of the symptoms that indicate that there is a mechanical problem? Are you already driving in a fuel conserving manner?

comment Windshield wiper only making contact on the ends of the blade
Pictures would help - Rory suggested the spring at the base of the wiper arm (near where the whole assembly pivots to wipe the windscreen). A picture of the wiper itself might help as well - maybe something is bent.

Yes, this sounds like there isn't enough tension in the arm.

comment Overheating & coolant loss in 1998 Subaru Outback
Amended my answer to recommend a coolant flush as the next step: it still sounds like "stop leak" is clogging your flow.

comment do all quattros have shafts connecting front and rear axles
You can decode your VIN by referring to the codes in the owners manual. You can also use some web services like the following: audivindecoder.com/vins/waudk78t59a020347

@Mauro, actually if you have the VIN and the owner's manual, you can usually decode it yourself.

comment Which color headlight is the safest?
How would you measure the safety of bulb color? Are you trying to allow for male colorblindness? en.wikipedia.org/wiki/Color_blindness#Classification Without a "safest" metric, this is a "what's your favorite color?" question which is directly addressed in the FAQ: mechanics.stackexchange.com/faq#dontask

Could you post a picture of what you're seeing? We would certainly expect to see a driveshaft running to the aft end of the car: fotos.autozeitung.de/1024x768/images/bildergalerie/2009/06/…

comment Use of Neutral Gear in Automatic Transmission
@Jesse, yes, you're correct. At the same time, so is Rory. If you're shifting to park, you're almost certainly motionless (or about to learn a valuable lesson). So you're going to shift from D to N to R to P.

comment What are the benefits of premium (high octane) petrol?
What's missing from your remark about "power adder"s is why they require higher octane. In the next bullet, you imply that any additional power will require higher octane. That isn't the case: a better intake and exhaust on NA cars will often improve power without impact on octane requirements. As written, this answer is incomplete, bordering on incorrect.

comment What are the benefits of premium (high octane) petrol?
"But due to the power adder they will require a higher octane": this is a specific place where compression and temperature are both important. The compression ratio on the Fiat Abarth is apparently 9.8:1 (higher than my old Mustang V8) with a peak boost of 18.1 psi. That means that without boost, the car should be able to handle regular gas. As higher temperature boost is added, low octane gas will become problematic quickly.

This answer is also missing discussion of temperature which is just as bad as compression in an ideal gas law sense.
