I'm on this forum to get advice too since I'm looking to purchase a 2014 A8 L Audi TDI now with 111k miles. I commute 100 miles each day to work and back in moving traffic averaging 80 mph. I have a trusted TDI mechanic looking at the car today for PPI. Car cost $26k. I'm NOT diy, just driving it myself to work and back for comfort. If it's a good car, what's the reasonable amount of life expectancy left on it, with the hopeful minor/ routine maintenance cost. 150k, 200k, 250k, 300k, or < thanks someone. Read some posts and replies already very informative and helpful so far, thanks again.
