Here are a few things that have gone wrong with my 2005 Roadster Limited, fortunately they were all covered under warranty. The list is just to give you an idea of what things cost (from the dealer) to have repaired, if out of warranty you would have to include labor charges also. Also keep in mind that your new warranty will run from the original "in service" date, I like to call it an "extra" warranty rather than an "extended" warranty. Most of my issues occurred during my 3/36 period, some right before my warranty was due to run out. IMHO it is worth the money to get the added protection.
