I perused the 5 pages of posts, and no one mention the widely publicized engine defects of early Boxsters.
The first few years had engine casting defects, IMS seal failures which basically leaked non-stop; people used to joke the Check Engine light means Change Engine. Many were warrantied, many were not .
They fixed the issue, however, if you see an early < '99, cheap car stay away.
Re: v. 113
-Porsche prestige v. M-B classic......dont do it for status....a recent Miata will be more fun/less headaches
-The Boxtser will have minimal long term appreciation....check 944 Turbo Values today
-The Boxster has minimal presence v. 113; its now dated, and looks generic
-The Boxster will cost a lot less in long run v. ANY vinateg car
-The Boxster will provide cooler a/c, better heat, sound insulation, better crusing gearing etc.
-It is not like a 911. I raced a 911 and Boxster back to back....Boxster had inferior chassis shake/shudder, dull steering/brake feedback, low power.
If you are looking for a modern summer roadster I would expand your search to TT, Z3, Z4; SLK and even Vette. I did the lightly used Luxo Euro GT in the 90s via a '85 M635 CSI and in retrospect should have gone with a Vette!
