I intend to live forever. So far so good......
and I guess that's how I treat my car.
Once any car gets over 5 years old things will go wrong.
A friend of mine drives a 1980's V12 Jaguar. It is pristine, but he needs to spend about $4,000-$5,000 a year on it to keep it going. His theory is that he absolutely loves the car and would be paying a whole lot more to buy a new car that he likes. BTW he is a surgeon and could afford to buya nioce Merc or Porsche, but just loves his car.
Rather than look at the money you have spent and feel bad about it, you need to look at it from another angle. Consider a forward plan to replace all the parts that are likely to wear out in the next 5-10 years. Calculate this in additona to regul;ar things such as brakes, tyres etc.
Make a list of all the parts that are "likely" to break (www.bmwe34.net) that you have not already replaced and build a schedule starting with the most likely. Your car will love you for it.
