I am considering buying a 2008 LR2 SE. It has had two owners and been well maintained as evidenced on Carfax records. It drives well and is perfect for my needs. Two things are concerning me and am wondering if those more familiar with the brand could give me advice. 1.) It has a barely noticeable rattle when driving. I did not realize it at first, like I had to actively listen for it. 2.) The Carfax report says engine mount(s) replaced. What does that mean? I wanted to buy an extended warranty for it but was told not available due to the age. Thoughts?
