Be cautious about using a forum to be your guild
There are many strong opinions here as well as real world experiences
You have to filter and you can get some good insight as to trouble areas to look for
Take Oil for example. It's all over the place as to what to use, but through all that is a common thread - what ever you use - change it often

You need your used car radar for any car but for high end sports cars knowing their trouble spots can help you weed out

You are looking at a 16+ year old car.
Low mileage on older boxsters has it's own debates as to being good or bad
Be knowledgeable about the models and what you want as far as options and let that help guild you.
For me it was the S model with 3.2 liter and I didn't want to have to immediately replace tires and brakes. The underside needed to be dry of fluids and all the other things to look for.

Good luck
