I drive one every day. I have a 97, the one you are not supposed to buy, and it has been flawless. 150k+ on the clock and I have not been easy on it.
As far as the newer one being warmer, you won't have that issue where you live, mine is plenty warm and I am in a slightly colder climate than you.
So far as getting a low mileage one, I would rather have a well maintained one that gets run more often, that is just me.
I am 6-4 and all my height is in my trunk, I have short legs and I fit in the car with no issues.
I love this car for the simple fact that it is fun as all get out to drive, comfortable, low maintenance, very reliable and did I mention fun?
Get used to the hair dresser jokes and inform people that you are an interior designer.
I would strongly recommend a Boxster to anybody who just wants a turn key daily driver that is comfortable.
The only drawback, carrying stuff. The wife wanted to pick up a shower curtain rod lest night while we were out and I just looked at her.........
You can forget carrying someone with you and any long guns.
I was asked what I would replace mine with when the time came for a new car and topping that list would be another one. They are great little (inside) cars. They are whales on the outside.
