As far as warranty stuff... I have a warranty through warrantybynet on my 92. Haven't had any troubles with them, though I haven't really tested them too much. They paid to replace a rear wheel bearing for about $300, but since that's less than the cost of my policy, it's hard to say what they'd do when it came to a tranny or something.

Anyways, they people there have always been helpful, and the dealer said they were easy to work with on the bearing issue.

It's up to you, but I'm glad to have it..
