Have a family member interested in joining -- the family.
Since the budget is dictating a used MINI, it would be great to find one that has a known history (read: club member) that would fit the bill. Only "must have" specs -- automatic (yea, go ahead and groan) -- looking at 2015 model year, but if it's close, send the details.
Preference is 4 door justa, but if you've got a 2 door and you're moving out of the country next week so have a fire-sale price on it, it might be of interest.

Send details and photos and I'll forward.
I'll mark the post CLOSED when a MINI has joined the stable. It will happen, just a matter of the right deal ..
