Yup, I saw 4 or 5 in the garage on Wednesday.
In general SFO is pretty good about having some unusual metal available from time to time.
Only hitch is that it's nearly impossible to confirm a reservation for one of these interesting rides for anything more than a day. Trying to book a weekly rental nearly always results in a "not available" message. Hidden meaning - we've got neat cars, but you're going to pay through the nose to rent 'em.
Anyway, yes SFO has Mini's.
