well u have space for one car so park the other car right outside the gate,simple isnt it 
like the family who lives in basement,they park one car inside,n the other outside the gate right next to gate n both cars chained to each other but obviously in the end that china lock is of no use used to lock the chain
P.S
i have space to park 5-6 cars in one lane,it would be so better to park the car at front n all oldies at back
