I have this car for eight years now. 227,000 miles later and I am still getting 45 - 50 mpg! I love the car but I hate the dealerships! Even though I have had minor problems...glow plugs, hoses, batteries nothing is ever in stock and takes weeks to get. I have found a local mechanic who works on the diesels and I'm very happy now. Change your oil, timing chain, and get your manifold cleaned at around 100,000 miles along with the innercooler and you will love this car. I'm trying for 300,000 miles as long as I can stay away from the dealership.
The great gas mileage, gas mileage, gas mileage!
Improve the radio, engine noise, add heated seats and mirrors, and diesels take some time to warm up.
