im out on the unichip....
i would buy a truck man (in addition to msp). im sure with the evo hood which I dont think lauren had rain guards for, the additional power you put down to the front wheels from your mods and your fmic you would rather not drive it in the winter anyways so there is a dual purpose.
just get a used truck. I found a deal on my 98 f150 for 7 grand I think last november. You can probably purchase it as a company vehicle, throw business decals on the doors and get all kinds of discounts and kickbacks right? pay for it with business money instead of personal takehome? or maybe you are doing that anyways.
If you are tired of the msp thats one thing but otherwise a decent full-sized used truck that will still be a reliable workhorse can be had for little money, spread the payments over 5 years and its not that expensive. I mean i dont know what truck you are looking at but brand new full size 4x4 trucks can get into the 30s pretty quick, so then you have one 30k truck vs. a 20k car you have invested money itno and (maybe) enjoy driving plus a 10k work truck that you wont hesitate to let other people for work (your manager) drive to take your trailer somewhere if you decide to setup at a fair this fall or something. From my own experience I cant tell you how much I love having a truck that I did not spend much money on, that came to me imperfect and so I never ever find myself concerned about beating it around a bit (towing a boat for long distances, going offroad, climbing into it when dirty from riding atvs, ramming atv into front of bed by accident, lending it to friend etc...)
anyways, no money for chip right now for me

sorry, sounds like you have plenty of other offers anyways. I was in a similar situation last fall when i bought my condo and a truck and since then, i have thought a bunch of times about trading both in and getting a nice truck like a silverado ss.....but having a truck that you can treat like a truck and a fun car you can enjoy like a fun car really is nice.
