Okay.
I can agree with the looks aspect (since I love the unique looks of the 2003/4 M45 too), but in terms of handling, the new M does have a significant edge over our years! The suspension is more modern, etc.
For me, the uniqueness of the 2003 M look is what led me to buy it ... my wife agreed heartily! In fact, we had gone in to replace my Q45 with a G35, we saw the M45 sitting in the showroom, we both instantly decided that we had to buy it instead - without even driving it!

Agreed!

Unfortunately, no simple or inexpensive way to up the ante on the M45. In the early days of the 2001+ Q45 (which has the same engine as our M45), there was a supercharger (may have been a turbo, I can never remember) for the Q45 offered by a company called Keuylian Motors. This would have been an awesome addition to our cars too. Unfortunately, the sales figures for the Q and M were so low that this product did not make it to too many of the cars.
Some of the Keuylian-equipped Q45's have made it onto eBay on rare occasions, by the way.
If you have the money to dabble, then a custom turbo-charger setup (and, of course, all the engine re-programming) is probably the only way to get any real power additions. This will be expensive ... probably in the $30k to $50k range at least, I would hazard to say, and more than I certainly would be willing to spend. For that kind of money, you are probably better off buying a more powerful car to begin with!
FWIW, as I recall, the Keuylian turbo/super-charger (whichever it was) was under $10k installed.
