I bought my 2005 Golf TDI brand new in February 2005. I love the fuel mileage - average of 46-48 mpg and I don't visit the gas station very often. It is a really fun car to drive with what feels like lots of power due to the torque. It is, however, expensive to maintain and not always easy to find a good local VW mechanic. VW dealer service always seems to be sub par (I have been to 3 different dealers for service). I still would not give up my car because I do love driving it!
I drive about 115 miles round trip to work. All I have ever done is change the oil (about every 12-15k miles), replace a couple head lights, and change the tires. My car has yet to need brakes or any major repair. The perfect stylish, fun to drive, daily commuter!
The engine is great and mates wonderfully to the DSG The car has plenty of torque and is responsive I am very disappointed with the quality of the materials used Car dealer service is very expensive. http://ontargetreviews.blogspot.com/2010/09/2005-vw-golf-tdi-20-comfortline.html
I have loved this car. I bought it because I drive about 30,000 miles a year. I drive about 65-90 mph on average, depending on traffic. I average about 42 MPG overall. This car has great power, don't let the 100 HP claim get you down. The true power comes from the turbo-charged diesel, putting out something like 174 ft-lbs of torque. The ESP has been great, saving me once. My biggest and MAJOR complaint has been the VW service. They stink. They deny everything they can. My mud flaps are cracking from the snow and ice build up. Diesel prices also are about 50 cents a gallon more than gas, so do the LONG math if you think you are saving money. I save about $1.40 a week, when you figure the difference in fuel.
I purchased the diesel since I do alot of mid distance driving. The performance is fine with amazing low RPM torque. Highway performance is first class and the fuel efficiency is even better than advertised. This was an excellent choice and was well worth the slightly higher sticker price. I saved that in the first few months on fuel.
