Last week I saw an add in the Philly area for a 1990 Coupe Quattro with low miles. It was black with some perf upgrades. The price was around $15k. Does anyone know this car? I cannot remember where I saw the add. Please help! I would very much like to purchase this car. Or if anyone knows of any other Coupe Qs for sale in the Northeast, let me know. TIA Tim ME
