I would keep it, but I don't really need another vehicle... My intention with it was purely as a weekend/afternoon project car.. IE getting enjoyment out of working on it a few hours a day. After that it would be our long-haul vacation car. So it was never intended to be a DD for me.
The problem is that I simply don't have a few hours extra in a day (or week, for that matter).. So instead of being enjoyable, it was stressful trying to carve out 3-4 hours on a saturday. Sad, because I grew up doing little mini restorations, but at this point in life I just don't have the time for it. Just too many things going on right now.
Engine transplant was worst case scenario, in case of a stuck valve or broken timing chain guides. I don't think either is an issue, it has the very distinctive "diesel" sound when warmed up, I'm about positive it's the vanos.
I did a lot of thinking yesterday and I'm definitely just going to sell it. I'm going to put it on CL this weekend.
