I put in an offer on a house yesterday. The garage is slightly below street level and the driveway is has a pretty sharp, greater than 180 degree angle off the street, ramps down, and then angles less than 180 degrees to flatten into the actual garage. So, something like this:

street____

********\

*********------ garage

Just eyeballing the driveway we knew getting the Lotus in was going to be dubious, so I drove it over and tested it out. No way. I'm going to try to find out if the driveway can be altered in order for the Elise to get in and out sufficiently but needed numbers.

Given a standard (no sport pack) Elise with clearance of 6" (did not account for the car sitting down with a passenger or two... significant?) and a wheelbase of 90.6", I came up with a maximum angle for the top slope of 181.5583 in order for the car not to bottom out in the center.

At the bottom of the driveway, again with 6" clearance and a 32" nose length, I came up with a minimum angle of 168.8514 degrees for the nose not to scrape.

I thought this might be of interest to others, and hopefully someone here can check my math, as it's been a while since geometry in Junior High. That top angle seems too small.

TIA!
