First Porsche
 

Greetings.
At the risk of touching off a war of conflicting opinions:

I'm thinking of buying my first Porsche and would greatly appreciate forum members' input as to which models and years I should look for. Considerations are:
a) Cost - No more than about $30K
b) Daily driver - It has to be reliable enough for use as a daily commuter.
c) Garage - I don't have a garage, just a long driveway. Based on past history with MGs and Alfas I've owned, and the fact that I live in rainy and humid Virginia, rust can be an issue with sports cars. Is this the case with Porsches?
d) Maintenance - Must be reasonably inexpensive to maintain.
e) Fun - Self-explanatory.

Thoughts?
Thanks,
Kevin
