My CPO warranty runs out in November. I'm debating on whether to extend it. My 17' RRS V8 only has 35K miles on it but did just have to replace one of the front CV joints which I'm sure was at least $2k. My dealer offered 2 options through Land Rover themselves: 24 months/24K miles for $5,928 or 36 months/36K miles for $6,701. The other option was a third party warranty through Axiom 72 months/75K miles for $9,137.
I plan on keeping the vehicle maybe another 2 years but maybe not. If I opt to extend I'd probably stick with the Land Rover issues warranty. I'm assuming that they would negotiate some on the price. I've had a ton of Lexus vehicles that never had problems so never even thought about a warranty. Needing a new CV joint at less than 36K miles seems kind of strange. This is what's making me seriously consider extending the warranty.
