Nine vehicles? I guess it depends on what kind of vehicles you have. Are you clogging up space with mini vans, Priuses, or AMC Gremlins? I'd say it's definitely time to thin the herd (although, a friend of mine has a Prius and he loves it!).
But then, I only have four, the youngest is the PT Cruiser of 2008 and the oldest, other than the Lotus, is my 2005 MB C230 so no danger of exploding clutches. Maybe you could pave your yard, fill in your pool, and hire somebody for the "other chores."
If you haven't retired yet, you might soon and then you'll need a project car. Another Lotus would fill that slot.
