 I bought my Jetta GLS TDI new in 2001 and it now has 197,000 miles and is going strong.  I commute 150 miles round trip daily, so I wanted a comfortable car with good fuel mileage - I have been well pleased. I'm considering buying another one, but want to hang on to this one. My only problems have been with VW service. I used to take it to the dealer since it's difficult to find a non-VW dealer mechanic, but have regretted the inconvenience and the cost.  When I contacted VW last summer after a dealer in SC had my car for 3 weeks and continued to give me the run-around, VW was not helpful and borderline rude. So, I'll keep my TDI and maybe buy another one, but find an independent mechanic.
