I have an 09 E70 48i the same color with similiar upgrades. It came with body mods but I added different wheels and caliper covers as you did. I was searching for a video on the remote start when I stumble across this. I really like what you've done with your ride. Gonna definitely look into the bluetooth device. You are absolutely correct about the V8 which I have. I wanted the N/A inline but got the V8 without researching. So glad I know how to work on my own stuff. Changing valve cover gaskets is no joke. Now that I've got that issue corrected I like it alot, especially after installing 2 great sounding mufflers. It turns heads now. LOL.
the v8 is still a good engine it has more things to fix if it breaks, but if you are handy with car its a nice car to own i always love the sound of those beast engine.
