Large trunks and bench seats . . . definitely.

I am probably one of the few who do not like the trunk release latch under the dash. With old style cars, valuables go in the trunk, and the car remains unlocked. Granted, it takes 30 seconds to hot wire the car, but if you get three-on-the-tree, few could drive it away.

water pump replacement, 40 minutes

No serpentine belts for the alternator either. Once I was able to get it to work temporarily with some clothesline I had in the trunk.
