If you bought 'em used, in reasonable condition, it was hard to beat a K-car for basic trans. Low initial purchase price. Low cost of operation. Reasonable fuel economy. Bought each of my daughters one when they started driving for approx $1,000 each. Liability insurance. One lasted two years till it got caught in a flood. One slid off a snowy back road into a telephone pole. Both daughters were O.K. afterwards. No worry about the vehicles...
IIRC, with at least one engine-transmission combination on the Citation, it required unbolting an engine mount and jacking the engine up to change the oil filter. BIL had a shop and started using a hole saw to cut an access in the front fender well. Sheet metal screwed a cover plate over the hole. Had to take a wheel off to change the oil. But, beat messing with an engine mount.
