Hi mate not read the treads all the way through, welcome, and in response, Ive not noticed the clutch to be heavy at all, infact its one of the best clutches Ive ever used, I use to have 3 different audi TT's and Toyota Celicas, And boot space, my sister has a Boxter 2.7 and I can fit much more in my boot space than she can, I am surpirsed that the boot space in the Z is quite big imo
I considered RX8 but whilst I personally like the looks I didnt like the fact of oil consumption every second time you fill up you have to check. Also the depriation is huge. But quite right it has 4 seats. If I was you Id do the following:
Sell your car put in bank, have kids then sell them on ebay, put money in bank, have wife, sell wife on ebay, put money in bank, go down to local nissan, put your name for new GT-R Jap import, hitch on trains for a month without paying, get new car 4 seats, very very quick, pick up hot stripper, marry her have kids, be happy, write a book on your life, sell the book, make millions be famous mention Zedrush in your book, hook me up with your hot stripper wifes mates, I get married, we sell wives, put money in the bank, buy a plane, fly to Brazil start a club, become muslim, have many wives, sell the kids, put the money in the bank, buy a bugatti veyron, be extra happy, sell me put money in the bank
Personally thats what I think you should do
