was a great car. I owned one for over 20 years. In addition to the carbs, you should check the ignition distributor. If your car is a U.S. model, it may have the "dual diaphragm" vacuum advance/retard unit. These can wear out over time and the weights in the distributor alone may not be up to the job.
Typically on the carbs, warped top plates [leaking air] worn out accelerator pump pistons or plugged accelerator jets and the most common culprits. Don't let just anyone mess with the carbs, they can be extremely expensive to replace; as I recall they were +/- $2K for a set back in the mid to late 1980s.
You really will want to get the car squared away before trying to sell it, as an educated buyer will know the these carbs are the weak point of the car.
