Should I or Shouldn't I, 914 conversion Options

[thetaxca]

Hello forum! new member here!

I recently purchased a 1973 914 2.0 all original (except for modified dual exhaust and requisite back bumper) with zero rust that has 128K miles. Paint code L30 Light ivory (but is pretty white).
It has original paint which is desperate need of being redone.

I have always wanted a 914 and this car as more than met my fantasy, however at 60 years old, it is becoming more and more difficult to get in and out of so I am thinking of selling.

I have 3 options that I am seeking advice on wanting to maximize my investment:

1) sell as is. I paid $15K
2) repaint (engine & glass out) and sell ($8K quote)
3) I have been offered a 3.0l rebuilt flat six with a 915 transmission (all working perfectly) for $12K that my Indy mechanic says he make work in the 914 for about $8K.

Looking for some advice from the experts out there.

Thanks
