I own both a 2012 LR4 & a 2012 RR Supercharged. They both have in excess of 100,000 miles but both have been maintained within regular service intervals and any issue has been addressed. My mechanic (not the LR dealer) says I should sell both because he thinks this vintage LR products are vulnerable for catastrophic engine failure. He’s had two of this generation with engine failures. Both of our cars run great but I’m now nervous since he’s told me to sell or trade them. Please offer your advice. LR4 - 125,000 miles —— RR Supercharged - 115,000 miles. THX!
