Itis, Yo! it just dawned on me, If you leave the removable steering wheel out of the car, you can lose even more weight. LOL.

Serious, 3500 is already steering towards middleweight territory. 200 Lbs is nothing to laugh at. The car will work that much less to get it to your goal.
I'd love to see that bad boy at a realistic 3200-3300 Lbs, but I'm afraid that entails lots of inventions and perhaps some $ thrown at it.

My car at this point is anorexic. LOL.
