No one advertises this any more because I'd say 95-99% of all vehicles sold in the US now have these features, maybe excluding a few fleet trucks.

You can also go get a small loan on a vehicle or something from a place that does payments for a stove or refridgerator, etc. 

Then you supplement it with investments as most of us do  and in whatever investment vehicle you choose to do..

They have even used crypto as a vehicle to collect payment and store wealth.

How are unregistered vehicles handled?  

I didn't even factor in the second vehicle + gas because the house is a small commute. 

A couple of years ago we met a retired investor who did a 1031 exchange into a vehicle which pays him monthly and will pass onto his heirs.

The facility called and demanded I install a handicap ramp and rails for her.

If you're on scholarship and/or your parents have college taken care of through 529 or other vehicle, AND if your passion is engineering, then I would say go to school, read FI and REI books as a hobby, and then channel that knowledge post-graduation to build the engineering life you want, whether that's your own company, or simply the ability to choose where you work. 

For example: if you are strapped for cash but are able to do some updating and rehab work yourself, a live in flip could be a strong vehicle to start out.
