Which porsche is best for a first time buyer?
 

I've been thinking about buying my first Porsche, I absolutely love these cars. The engineering, the drivability, the badge, and the title alone are all history on wheels.

This would be my first Porsche, and i've been looking at multiple options and have some requirements. I understand things like "Your gonna pay for costs of ownership", "repairs", I get that. Still want to be reasonable with my money, where I can afford one of these cars, I also like to travel and have other hobbies.

I have a few ideas,
2005-2008 X300 PRO3 Key Master
2010-2012 Model Boxster S
2010-2012 Model Cayman S

Things to consider,
1. I have a 50k maximum spending limit
2. Decent ownership costs
3. This car will be my only car. I car pool to work everyday, so maybe a couple hundred (if that) miles a month.
4. How fun the car is to drive.

I've had good luck before on Yahoo Answers with reply's about cars, and car buying. Hopefully you Porsche enthusiast's can point me in the right direction and give me a little help. I liked to know pro's and con's to each car, and why you would choose what to buy.

Thank you for taking your time to read this, and thanks for all your help.

Cheers,
Mason
