Hi Steve.
Not knowing you it is difficult to advise, but given your two post I would say:
1) spend a lot more time reading on this site - a lot of good info that will answer your questions.
2) Get to see some Backdrafts in live...
3) Get your priorities in order - color/engine/options...
4) BUT if you are in a hurry

is a very good option - I would offer doctodd $42'
(The R engine is not for me - the SR/TW is much easier to drive down town - but that's me
)
