There is some middle path - ie buying that beamer, few years old, for say 25% of the original price. Not because of some immaturity, need to compensate for something missing in life, just a desire to have a good car that does on the road exactly what one wants, whenever one wants and covers all one needs from it. Sticking with it for 10+ years, having it serviced at good unofficial mechanic, so it costs +-same as crappy cars people buy new for much higher prices. Which means simply not caring about the cost, in face of overall added value to life.

It brings long term happiness. Satisfaction. Its just great. One of best investment in quality of life I ever did.
