Compared to what I can buy for the same money, the M45 is a very average performing (in a straight line - the handling is VERY good I will agree) car. I did all the comparisons when I bought my M35 2 years ago and the M has fallen even farther behind since then. Comparing 2 year old CPO cars at the time, i could have bought a CTS-V (400HP) for about the same money. Some 545i's I looked at were more than the M35 I bought, but similar to CPO M45's. That's just two off the top of my head - there are plenty more (E55, S4, RS6, etc). Any will run and hide from an M45. Easily.
Again, the bottom line here is an expensive lesson I learned a long time ago. I've tried to pass this on to others, but some people just don't want to hear it.
With very, very few exceptions (usually turbo cars where you can increase the boost), it is ALWAYS, ALWAYS, ALWAYS cheaper to buy a faster car than it is to modify your current car. When you dump money into your car to make it faster, you end up finding all the weak points you've exposed by adding more power. You void warranties if you go too far, and you ALWAYS lose on resale because the next guy (rightly) doesn't want to get stuck with a rolling science experiment.
Seriously - who is going to dump $15-20K in an M45 turbo/blower/motor rebuild to get it up to 450-500hp? Then you will start breaking the transmission or rear end. Then you'll realize you need better brakes. It just goes on and on...
Wouldn't it have been easier to just buy a nice clean CPO M5, E55 or CTS-V to start with ? The M45 is not in their league and never will be. And you'll come out far ahead in the $$$ game by having a car engineered from the start for more power.
Am I less of a "gear head" for pointing out this obvious solution ?

Very good points indeed, but what if you don't like those vehicles. What if the M45 is more comfortable. What if "yadda yadda yadda..."you get the point. Buying new versus buying used is a different story all in its own also. The price that I bought my car at plus $5K I'd still be way cheaper than all those rides you pointed out. Hell, even if I went up to $10K I'd be just a bit over but not by much. Trust me I looked and I honestly wanted the M45 as it is the most optioned out of all those cars. When I made the decision to buy I realized that the M was out muscled but I figured a few mods would bring it to life. I just didn't realize how bad the aftermarket support was for this vehicle. Lucky for me I can do all the fab work myself.
Here's a cost breakdown for mods cheap to most expensive and I'm talking DIY and store bought.
Ken's Amsoil filter and JWT POP look alike Air Intake + heat sheild - $75 plus a little diy elboe greaseKen's X pipe mid exhaust mod - $90 for the X pipe, $80 for additional piping - $170Non Verified 300zx TT 3.69:1 R230 rear diff ~ $200Weopon R intake (do not recomend using their filter) - $220Injen CAI (only recomend to use the amsoil dry filter version and only on it's own with stock exhaust) - $270Megan axle back (CHIMADENA) - $280Megan Mid pipe (CHIMADENA) - $330Various HKS axle back ~ $600-$900Element 114 full (fitment issues) - $600-$800Stillen Full (Best of the bunch but cannot confirm fitment) - $900ish
Megan coil overs (CHIMADENA) - $1000TEIN Basic Coil Over - $1000
G37sport BBK - the entire kit Front and Rear can be purchased as cheaply as $1425 - add slotted/drilled rotors and Hawk pads and it only rises slightly
TEIN FLEX Coil Overs - $2000
UpRev ECU tuning - $400 plus dyno time - currently not available till I get my crap together and be the guinea pig but if someone were in the central texas area you could get it done in a day.Technosquare ECU Tuning - Don't offer our car but they do the FX45 with good results - SoCal area members can go direct and get the mod in a day
Turbo - This is a little tricky, depends on what you want and your fabrication skills. I'll assume that everyone has to pay for labor using an STS generic turbo kit for $3k plus $2k in fabrication at most - then either a JWT rising rate FPR and 255lph pump $400 or an UpRev tune $400DIY'ers can have it for much less by utilizing their fab skills and sourcing alternative parts to create a remote mount turbo setup.
Supercharger - only one kit was ever made for the VK45DE engine for the 2002 and prior Q45 w/o drive by wire. These kits were limited in numbers and very expensive upwards of $10k. However sourcing a take off supercharger from a ford lightning/mustang/shelby gt500 is fairly cheap but fabricating the kit to work correctly would be the most expensive aspect. I would assume $5k would be the cheapest for a custom supercharger setup.
I'd be safe to assume that more money is spent on wheels than actual mods to the car. I've seen some spend $4K on a set of wheels. To me that is rediculous, to them it is worthwhile. Some say that my mods are rediculous, but for me they are worthwhile. Do you see me or any other person calling them knuckle heads? Do you see anything negative from me about adding body kits? I don't like it and it's not my thing, but I support them still positively. Only time I get negative is when that negativity is oppressed upon me. Back me into a corner and I'll react - simple as that. Anyone - Call me a knuckle head, but you would be the one that is really being the knuckle head for your directly insulting acusations. I guarontee that if we all met up in person we would be as friendly and as cordial as possible because (and I hope) We all realize that this is a web forum to share thoughts and information.
