I have a lease on an A4 that expires in 30 days. I was planning on replacing it with a new A4 but found out the manual won't be available until July. So my wife and I decided that we would get a used LR3. I have been looking for a 2006 with 25,000-35,000 miles. I recently found an 06 HSE with 24,000 miles for 25,000. We went to test drive it and loved it, planned on buying it until we ran a CARFAX on it. We found out that it failed its last emissions inspection in 08 by the previous owners and hasn't passed since. I still have the opportunity to purchase this truck but am concerned as to why a 24,000 mile vehicle would fail an emissions inspection. I also heard thru a LR dealer that this vehicle was declined warranty service from LR. I feel like this is a deal that is too good to pass up, but don't want to get screwed with a vehicle that might be plagued with problems. What would you do?
