32 and lives with his mom? At first thought, that's sad - what a loser. Then you think maybe his mother has a condition and he's doing something good and trying to take care of her.
Now as far as his choice. While I don't agree with it, you have to remember what country he lives in....I think Devo said it best, "Freedom of Choice". If that's what he wants - so be it. I think he should be allowed to fix it up and make it nice. That being said, BMW owners make me cringe as it seems as though I just have a personal prejudice towards them. Mostly because they drive like nuggetheads (most, but not all).
With that lift kit and those tires I think its a safe guess he wasn't breaking 10mpg.
Still, IMO if he doesn't drive like a TypeA personality would and doesn't hurt anyone let him be. I know he's not helping the enviroment but no reason to screw something up someone worked hard for.
