My Situation to Ownership - Your Advice???

[luxury1]

I am 28 and am building a house. In the 3rd bay of the garage I wanted to put a '05 or '06 boxster. My wife and I already have cars that we own and this would be our 3rd fun car (summer and such) so we are not going to be putting on a lot of mileage on it. We are planning on having kids in the next 2 years. Thus, my question is should I lease or buy? I have been reading a lot of maintenance costs of the higher mileage and I am not sure which way to go especially since the thought of walking away is attractive. Any input would be GREATLY appreciated!

Thanks!
