...  Factor in other annoyances like the handbrake, seats that give me back ache and I think its doubtful that I’ll be driving new Porsche.

Thank you for that very detailed report.  It's a great read and your car looks fantastic - I especially like the how well the 18" wheels look and flow with the body style of the 987.

I have one question though, if you care to enlighten me.  I too do get quite a lot of back ache from driving the 981.  While it must be the seats it has not dawned on me what it really is.  I am surprised to read that I'm not the only one who experiences this nuisance and even more that this appears to be a phenomenon completely unknown in the 987.  Why is t that?  And what is it?  What is the difference in between the seats of the two model generations?  I'd like to know and understand more about it.

Many thanks.
