I've told this story many times here, but for you benefit....
I bought the second 04 here in Lubbock, Vin 2200. I planned to drive it t 50k then trade fror a new one just to protect myself against later mileage problems than might pop up on the new model. (like carrier bearings)
When I got to 48k, went to my dealer to buy a late model 06, but we could not find one that had all I wanted like rear diff. So I had to wait a few months and order an 07 set up like I wanted. This put me over the 50k, so I bought an extended warranty for 75k for about $1100. Subsequently, I had 2 repairs for well over the $1100 and all I paid was the $100 deductible twice. Money in the bank, right?
The topper....when my 07 came in with 54k on the 04, I cancelled the extended warranty and they pro-rated me $900 back.
Simply, I would not drive a Touareg that is over 50k (36k on the 09's) without an extended warranty. They are just too expensive to repair.
In fact, it won't be long til I shop for a new extended warranty on the 07.
You are just betting against the house if you don't get one IMHO.
