Sorry but I gotta say dont do it. Not trying to be an ***, but..
1. You have limited mech skills
2. Both you want kids so you hope to sell it for a minivan in a few years?
3. Worldwide pandemic.
Sorry just my opinion, if my friend and we were shooting the **** and he had the same scenario as you I would tell him the same thing.
You got a good looking girlfriend, ride her :poke:it will cost u less(hopefully)
Just my opinion.
