Because of the constant complaints about quality you read about on this board, one would think an extended policy is a good idea. However, with over 400,000 TT and 5vers sold a year what are your odds of needing it?
The insurance companies think the odd are in their favor.
If it is not an undue burden, then it is worth the piece of mind. If you tend to fix problems yourself you may never need it. It is definitely a gamble.
In my case I purchased and extended warranty on my used TV because I intended to do a lot of towing, hence increasing the possibility of problems. I was also leaning towards the purchased of the insurance for my used TT for the same reason; I use them a lot. Finally, at the time I also asked the DW, "happy wife, happy life". She thought it was affordable and worth the peace of mind.
In my case it was a good gamble, after only 3 years and 25,000 miles of towing, I hit a road hazard, which broke a spring, taking out the tire, rim, axle, steps and stabilizer jack. The damage was covered under the road hazard option with no problems.
Who knows, if I only towed a couple thousand miles a year, I may never have needed it. Also I had a $500.00 deductible so minor repairs like the refrigerator igniter and shelf runner mounts I repaired myself.
Like my car insurance, I have paid for years and the amount I have paid in far exceeds the amount I have received for the dents and dings they have paid to repair, but I still need it.
Good Luck
