My friend is swapping cars with the owner, so it may be possible to keep it at my house overnight and return it to him in the morning. Of course, I will have to give him my E300 TD ...

My concern is I am not mechanically inclined, nor do I have time for major engine work with 7 children. I keep hearing how nice these older 300s are but I do not want to spend all my spare time taking this back and forth to the shop.
