How long is the warranty on Range Rover sports? Mine was first registered in Oct 10th 2006 . Is mine still in warranty?

Please tell me it comes with a 3 year warranty...

Yes it does

phew!

It may depend on the country, here in the US the factory warranty is 4 year or 50K miles, whichever occurs first. Since I drive my RRS about 30K miles per year , if that was my car I'd most likely be out of warranty already... How many miles do you have on yours? 

Vehicle warranty
Should any part of the vehicle require repair or replacement as a result of a manufacturing defect, the part will be repaired or replaced completely free of charge by any Land Rover dealer/Authorised Repairer, regardless of any change of vehicle ownership during the period of cover.

Tyre defects are covered separately by the tyre manufacturer. However, your Land Rover dealer/Authorised Repairer will assist you with any tyre claim.

The vehicle warranty starts on the day that the vehicle is delivered to the first retail customer and continues for three years unlimited mileage.

Note that only genuine Land Rover accessories fitted by a Land Rover dealer/Authorised Repairer, within 1 month or 1000 miles/1600 km (whichever occurs first) of the handover of a new vehicle will benefit from the same warranty terms and period of cover as the new vehicle warranty.
