Buick Regal Sleeper with MD inspection buying option

Near perfect condition aside from cosmetics. Engine and tranny are tops, with zero engine lights or computer codes. Over $4k in new parts over past 2 years like control arms, wheel bearings, etc.
Mods:
Removed 108 mph speed limiter. This is why it's a "sleeper". Has gone 142 mph.
Lower running temperature (I was tired to replacing the rubber and plastic).
Special oil filter (10x smaller 2 micron vs. 20 for the particles getting removed)
Non-Android (for more privacy) head unit with GPS and wired backup camera (for less radiation). GPS beeps high only if nearing a speed camera and speeding x% over.
Replacement of cd storage area with tray.
Removal of speed-dependent power steering (I like predictability).
The Maryland Safety Inspection will cost an extra $285 – $85 for the inspection itself and $200 to cover my waiting time and any new problems that arose since the last time I was thinking of selling. It's rare that a dealer will sell a 19 year old vehicle that's Maryland inspected instead what they do is they sell out of state where there's no inspection. So blue Book prices for a car like this are too low.
Price is firm. Ask for a much, much longer description, and more photos in higher definition.
