Good point. I figure I have 20 more years until I have enough saved for retirement. I was going to bump my retirement contribution this year from 12% to 17% (not including match) and was going to do that regardless of car buying. But my nest egg is nowhere near where I need it to be. I'll probably let my savings rate inch up as the years go by--but at 20 out I am dubious that my current fleet will be around at that time.
Don't forget, my fleet still has to pass yearly inspection, and three of them have to pass emissions. Cheaper than a car payment but all of them are on the hook for trans failures, cat failures, etc. Except the one which can now legally have the CEL ignored.
It of course has rewarded me with delayed engagement into drive over the last couple of years.
No, I need to talk myself out of changing my fleet once again. 20 years will come and go faster than I think--the last 20 certainly did. This thread is slowly getting me there.
