Build a Bigger Grarage or Sell a couple cars ?

[67since67]

As was said earlier, don't jeopardize retirement, or fulfilling your bucket list, just to have more cars.
That said, the best thing I ever did was consolidate everything onto one property, laid out such that I can back out and drive any car at any time. ROI? I don't know, it makes me happy, and I didn't build it till age 64.
It depends on the neighborhood. In my little subdivision lots are measured in acres. A neighbor has a barn (a beautiful 1,800 sq. ft. stable actually).
If not for cars, my place could appeal to someone with a motorhome and a tag along trailer, or other types of toys. The cost of off-site storage is crazy these days!
