I think I've seen that it's possible to backdate the instrument cluster, but I'm not positive.

I know it’s possible to fit a 5 gauge 996 cluster in the 986, and do some wiring/programming to make it work. But I thought that was all that differs between say a 1999 986 and a 1999 996. Interior-wise, of course, sans the back seats.

I voted boxster, would have voted neither if the option existed.

09 and up seems to be the only boxster cayman worth owning unless you like scored cylinders.

I took the same approach! Beautiful car btw, I love the RS60.

They are almost 100% identical. Most parts interchange. The only thing that could feel cheaper are options between cars. Seats, dash, door panels, trim pieces, all the same.

I have had a 2001 Boxster S and now own a 2004 C4S coupe. I'd vote C4S but loved the Boxster. For me the Gen 1 Boxster was a bit too small in terms of interior room for my frame or I'd probably still have it. I needed another inch or so of seat travel. Longer term I'll likely get a 2009+ Boxster or 911 Cabrio as I miss having a soft top for our climate. The full leather on the C4S makes the interior feel much higher end.

Full leather is definitely more luxurious but you could get it with a Boxster too. Mine has it.
