Hey Cliff rennlist is a great place to learn about 911s.
I bought my '68 912 about 5 years ago. Have worked on it extensively. Bought the '88 3.2 Carrera about 18 months ago and it is my daily driver. The '88 I did find in Golden on craigslist. I had looked for an '88 or '89 targa for almost a year on line.
A couple of thoughts there is a great book on buying used 911 by Peter Zimmerman (8th or 9th edition). there is a link at the top of the 911 section. The important thing to really understand is that you do want to have a shop do a Pre Purchase Inspection (PPI). Cost about $200 (2 hours labor) but could save you thousands!!! seriously.
SC is a nice car with the 3.0 liter engine.
Not around this weekend, but next weekend I should be if you wanted to stop by see the '88.
