I'm coming up on the 50,000 mile warranty expiration.

Wouldn't want to guess! My personal favorite, is still 'CONSUMER REPORTS USED CAR BUYERS GUIDE', they may have it listed and that would give a good general summary of known problem areas. May be able to access on-line , or they are available at most good book stores and magazine stands.Been using it as a guide for over 25 years and it's always been about as accurate as you can get ,for trying to predict the future!

Good idea...thank you for your guidance in this matter.

Good luck , hope you can keep enjoying the ride as long as possible. (they do look nice , seen a few on the roads on my commute!)
