Welcome to NICO!

Are there any hints or tips anyone would like to offer? I currently have a 03 TL Type-S. Never owned a Nissan product before, so I'm bit nervous of the unknown.
The M45 (V-8, RWD, lots of low-end torque, etc.) is potentially going to be a bit of a change from your TL (V-6, FWD - I think, lower torque, etc.).
In general, the V-8 in the M45 is going to be smoother, quieter, more fun to rev to high levels, drive fast, etc. and I would pick it over a V-6 in the TL any time! I greatly prefer muscular RWD cars with V-8's.
In terms of reliability, problem areas, etc., please look at the posts about engine oil consumption - some of the 2003 and 2004 M45's were not broken in properly, and the engine is susceptible to high oil usage.
FWIW, I love my Infiniti M45 (and would not change), but I can also say that my wife's older 1997 Acura CL has been one of the most reliable cars that I have ever owned. Your 2003 TL is probably extremely reliable too - with the exception of the transmission issue that I know exists in those model years. In recent Consumer Reports rankings, Acura shows better than Infiniti on reliability in general.
Of course, long-term reliability of a particular car is dependent on how well it was maintained. If the 2003 M45 you are looking at is a lease-return, then I would be concerned. Unfortunately, most lessors - of any car - tend to not maintain properly, since they know they are going to return the vehicle and let the next owner deal with the resulting lack-of-maintenance problems.
The bottom line: if I was the original owner of a 2003 Acura TL, and I had maintained the car properly and it was running well, then I'd perhaps not make a switch to an "unknown-maintained" 2003 M45. Even though the V-8 would be awfully tempting, and I might do it anyway!
But, would I consider getting a 2006/7 M45 (or even a 2006/7 M35) over a 2007 Acura TL? For that matter, would I have bought a 2003 M45 over a 2003 Acura TL, four years ago? Without question: in a heartbeat ... to both those questions!
The new M beats the new TL handily - without a doubt. You just have to look at the April issue of Consumer Reports to see why others agree too!
