I can totally relate. Growing up, my dad had a 1972 Datsun 240Z. That car would flat out haul. One day I would love to get my hands on one, although it is not cheap like it was in the seventies.
Nice that you are able to spend some time with your dad. Mine passed away a few years ago, and I often wish I could have spent more time with him. It is so easy to get wrapped up in our lives we lose sight that other parts are passing by. Have a blast, and keep making those memories with the ones you love.
