I did a lot of research on warranties a few weeks ago, i have a 2001 with 54,000 miles. I came to the conclusion there are an awful lot of warranty companies out there with some dubious practices, stay well away from Continental, their sales people called me constantly and got to the point of insulting me for not taking out their warranty, i had to hang up the phone and tell them not to call me back ever!
The best coverage is an exclusionary policy which lists whats not covered rather than what is. I settled on 1sourceautowarranty.com they seem to have a decent record, checked out BBB, online reports and customer reviews, their sales people are also polite and do not harass you, i have a contact Dale Easton, email deaston@1sourceautowarranty.com i was quoted $1550 for 4 years 48,000 miles from the date taken out, this was their highest plan with the most coverage.
I havent comitted to a warranty yet, but if i do, so far i like this one the best.
worth checking out.
