I like it as a car because its reasonably uncommon.
I also take a bit of pride in it, knowing I fitted the engine, box, brakes, etc... (virtually everything mechanical) myself.
I've done a fair bit of the work on the car single-handedly. It feels almost like I have some personal stake in its wellbeing, like a responsibility for it.

However, in comparison to my misses, my dog or any of my family it means nothing. I sold my 'fun' cars because the money they took would be far better spent on the misses or house.
