Houston huh? Hope the A/C works good! Just kidding, we have had a 96' C280 for about a year and overall are happy with the car. We have only put about 15k on the car, so the verdict is still out. But my wife loves her Benz and will own nothing else!

for a ball park on pricing.
Just be sure to pay close attention to the structural welds for any accident evidence to see if they look original, have a M/B mechanic check the car out completely, a Vehicle Inspection is a must when buying a car with such high cost potential in regards to repair! Well worth the $125 that is typical, you won't be sorry.
With that said, if everything checks out, you will enjoy the car greatly! Good power and if you ever decide to do any mod's in the future, the C-Class will look great.
