Persist hon....isnt any car expensive to fix ?? Yeah, if it needs a new motor, sure thats gonna be expensive, but if you shop right, honestly, you will find it totally works for you...
YOU can also walk down the centre of the car from driver seat. So say its raining, i usually throw () al kids in the car, shut the doors, then climb in drivers seat, walk down the 'aisle' and buckle them up...without me/them getting rained on.

Look at private sellers too....lots online with families that have out-grown the family bus and looking to downgrade.....

GL...let us know how you get on....
