hey guys, i've always liked this model porsche since i was a teenager. i loved the way they looked and sounded in movies like Weird Science, Scarface, and Risky Business. i'm considering one in the 86-90 years up to 15k in price. what can i exspect as far as upkeep,maintenance,reliability. i know they are getting old much like our buicks. i know they arent the fastest and are a little heavy. think they ran low 14's high 13's. any tips or links will be appreciated. thanks.
