I've got an '86 5000s non-turbo and have been looking to add to my stable. Two '86 5000cs turbos were adverstised today for $3300 and $4200, first with 135k miles and second with 117k. I saw the first but will have to wait until tomorrow to see the second. Are these prices ok? Or should I wait for a quattro to appear. Thanks for any help. Shea
