I have not regretted the e36 328is purchase. I have been enjoying driving it. The gear engagement is really something. A few weeks ago I had the front subframe out, fixed the leaks, replace steering rack, control arms, etc, etc, etc. New kwv1 coilovers are riding great. Apart from a piston slap when cold and a couple areas of rot there's literally nothing wrong with it
I'm not sure what to do with it. But for now it is a fun daily driver. I did a engine flush and it actually kind of rips. Sounds great.
The x5 has been a real mess. Since acquiring it 4 months ago i've worked on it about 120 hours and have driven it about 8.
Maybe after this weekend again in the garage it will finally be good.
