Questions on Argentina/Uruguay Temp Import & Bike Storage in Buenos Aires/Montevideo

[arooni]

Hi everyone.. I posted on a similar topic before but it was rambling about non consequential stuff. This should be more on topic and useful to other travelers.

Here are my questions for you

I've been reading different threads on the subject, but I'd like to ask the following questions I couldn't discover from my research.
1) It appears as though Argentina will give you up to a 8 month temporary import visa upon entry if requested... but that sometimes that they will not give you this visa, and give you a shorter length like 3-6 months. If I can't get the 8 month, it seems risky to try to store the bike in B.A. and fly out of there. Question: Can I rely on them to get me an 8 month temp import visa for my bike?
2) I have read that only if I have the 8 month temporary import for the bike, will I be allowed out of the country (the 3-4 month won't work). Is this true? Must I bring the temporary vehicle import to the airport to checkout of the country?
3) Various threads have indicated Uruguay will give me a 1 year temp import at the border with no hassle. Question: Do I have to pay for this visa, and do I still get the 1 year? Can I leave Uruguay while my bike is there? Do I need any documentation or paperwork at the airport when leaving? If they don't give me the 1 year visa, what amount are the border officials giving instead?
4) If you're me, and assuming you want to be home for 3-4 months, and 1 month of transit to get to B.A., do you leave your bike in Buenos Aires or do you leave it in Uruguay? (I've read Argentina has *very* stiff penalties for overstaying your temporary vehicle import, including high fees and impounding. Not sure I want to risk that.
5) IMPORTANT: If I happened to be flying back into Argentina or Uruguay, is it permitted to bring parts for my bike? I.e. two tires, brake pads, steering bearings, rear wheel bearings, spark plugs? Or will this stuff get confiscated at the border? This greatly affects my planning.
6) I've heard that you can bring back stuff like Apple Computers to Argentina and sell them to cover your airline ticket. Is this just rumors or is it true?

And finally, I I could *really* use your help
If you live in Buenos Aires or Montevideo or nearby, (or know someone who does) and have a safe place for me to park my bike for 3-4 months please get in touch via PM or email (david AT davidparkinson DOT com). This is the most important thing, as without a safe place to store my bike, I don't feel comfortable booking airline tickets.

Many thanks in advance. Hit Ushuaia, and now on my way back to the USA, thanks to my new chain/sprockets which I replaced in Punta Arenas today... thanks to a realllllly long lever arm, and a block of wood wedged in the rear wheel.
