Well...we answered that question...

We bought a pre-loved Santana Visa Tandem last night. There will be pictures once it goes to the shop for a once over. We took the element to pick it up. The passenger's side front seat slides up, and goes forward a little. So....we just barely managed to get the tandem in. No room for passengers (DH rode in the back with the bike). The only way to actually fit a tandem would be to put all of the right side seats in bed mode - but that means you'd have to be very careful about grease....

Just something to think about
