Well, my 2000 Jetta has over 234k miles on it and is still running strong with no issues. Although I recently retired and the number of miles I drive will go down as my daily 84 mile commute is over, each fill-up is staying at or above the life time average... see signature!
Now, its understandable that some maintenance issues are not too far around the corner. But, most of them should be relatively inexpensive compared to monthly car payments. Also, there is the added benefit of lower property tax on an older car. I still maintain full coverage insurance, however, that cost is lower than for a new vehicle.
Since my first VW diesel, Janaury 1980, I have enjoyed the lower price of diesel vs RUG for many years. So, I consider the current prices a bump in the road. I am an optimist believing that an alternative fuel for the diesel engine at a very competitive price is not far away.
My intention is to hang in and be loyal to the engine I have come to really appreciate !
My two cents worth!
