Godfrey,

The co-location of steering and drive makes even the simplest FWD car 
more mechanically complex than a RWD car, even if both have fully 
independant suspensions. The CV joints and drive shafts are what drive 
up the cost of repair, sometimes by quite a lot. Also transaxles are 
more difficult to work on as they are more mechanically complex 
(Primarily due to co-locating the differential and transmission).

Ironically FWD is once again becoming restricted to smaller cars where 
it belongs as the superior handling and accelleration characteristics of 
RWD cars is making them more popular once again. And FWD cars only have 
superior traction under very limited circumstances. RWD gives superior 
traction under accelleration and also loses traction much later under 
hard cornering. FWD overloads the fornt tires cause earlier traction 
loss and a tendency to understeer badly when things go wrong.
