Boxster-reliable daily driver-maintenance costs?

[dannosny]

I drive a BMW 99 323ic (conv.) 5-spd manual and use it as daily driver (18k annual miles-123k total miles). Since buying it 3 years ago, this car has been a great reliable daily driver only requiring regular repairs and maintenance which my local garage has handled. I was planning to move up to a newer 300ci (conv). A friend recommended a boxster so I test drove a 99 and was immediately hooked, albeit the 3.0 bimmer might be a tad faster. However, the bimmer cannot compare to the Boxster’s exhilarating handling, wow! After hours of internet research I have concerns of the boxster's reliability, repair and maintenance costs. The local Cherry Hill, NJ Porsche dealer appears to be the only maintenance/repair shop in my area. I currently have the 99 biimer up for sale on auto trader and looking for a 2000 Boxster (possbily an S). I think 2000 started the increase for the standard boxster to 217 HP and the S went to 250 HP. I know miles are commensurate with the selling price of any vehicle, I am just concerned about how many miles the boxster might have on it when I buy it and what are going to be the cost of the next scheduled maintenance/repairs. Can anyone in this forum tell me what is the required maintenance, at what periodic mileage intervals and what are the expected costs? What are the cost of regular repairs, e.g. brakes, oil changes, filters and other regular ones? Do oil changes cost $140? Also, how reliable are boxster’s as daily drivers? Is there a web-site to use a resource? I know this a lot to cover. I just don't want to spend a lot after the initial cost of the boxster. I would really appreciate anyone in this forum sharing their knowledge. Thank you.
