However...
There is a far higher risk to the leasing agency when considering a car. It's mobile, subject to all kinds of environmental and safety issues, is expected to require maintenance, can be modified, and so on. Therefore, the lease of a car is much higher due to the exponentially higher risk of damage or loss to the leasing agency. Further, if you don't pay, they have to find you.
With a 942, you really can't modify it, don't carry it around, if you don't pay they immediately shut off the use of it, it can only be used for their service, and drunk driving has a completely different meaning

.
So, my own opinion is that the $250 is way too steep. If you were promised you'd get it back, then no problem (assuming we could every believe the E* promises). In that case, it's just a deposit.

Who pays thousands of dollars to rent something? (car) Quite a few do.
You can lease a 942 for a bit over 1/2 the purchase price over 3 years.
