I'm looking at a 2008 Acura MDX with tech package for sale. It has 83,000 miles on it, and they're asking $14,500. It has not had the timing belt change on it yet. The owner said that their mechanic told them it does not need to be changed yet. The vehicle has never been wrecked. What questions should I ask the owner? My current vehicle is an '05 Tundra with about 180,000 miles. What maintenance costs should I expect over the next 50,000 miles, aside from the timing belt? Thanks in advance!
