My first project, without ever having worked on a car before, was to change the driveshaft on my 82 BMW 320i. Since then I had redone the stereo with all new speakers, a new head unit, a 6 disk changer, and 2 subs in the trunk. I redid the suspension with some lower stiffer springs and good shocks. Then I pulled the engine out. And it's been sitting ever since, because the head was a total loss and I didn't trust the block. I got a new engine from a 91 318i to put in it, but I haven't gotten to it, because I don't have a hoist, and I don't have any way at my house to fab the custom mounts it'll need because of the different shape of the engine. Oil pan is deeper, so the engine has to sit a bit higher in the bay.
I haven't done a whole lot of maint work on my truck, because I haven't had the time I did in high school, and I can't go for more than a day without my truck because of my commute. I wish I could conjure up the money to get parts n tools to finish my car, but other things keep popping up that have higher priorities.
