you know that 1999-2003 covers two different chassis.
and C240's are due for a recall that was announced last week.

About the C240 v-6 engine, it is very nice, smooth. If someone is considering a 203 chassis 2001 to present with a v-6 engine it is a great car.

Soon the new 350 engine will be in the C-class and that should be something.

If buying used, you need a warranty backed by the manufacturer that covers at least a couple of years and tens of thousand of miles.

Consumer Reports dosen't recommend the C-Class as a Used car recommendation. But considering they vote the Buick LeSabre a best buy, make of it what you wish.
