On my first car, it would have been the engine I bought.

Previous car...would be wheels (Prodrive P1)

And on my current car...an OEM center armrest? Probably won't be much else since its a commuter car first a foremost.

On my wife's car it would also be wheels (Volk TE-37)

HID retrofit with honda s2k projectors, that ran about 800 for all the parts. i was doing a lot of night driving between NYC and Pittsburgh, definitely worth it.

The headers on my goat... $1200 or something... highway robbery.

Same here. For my headers, with cats and coating, it was close to $2k. I ordered them from the exact same place.

very nice...

i was about to retrofit mine w/ Acura TL or TSX projectors, but i saved some money by getting some DDM HID's and sticking with the OE projector (i have the euro JZA80 headlights, which have glass covers and a much nicer projector & beam pattern than the JDM/USDM headlight housings).

I'm not going to include the wheel/tire package, so I'll go with my Stance coilovers.

 

[Imported]

Xida Coilovers for the Miata.. about $2200.

If my stereo system counts.. it was more than double the above amount for the G35.. :$

Garmin nav - $100

 

[WackyDan]

$1700 for my Retrax Pro bed cover. Expensive... but well worth it for a vehicle I'll be keeping between 10 and 15 years.

Edelbrock Performer RPM cylinder heads for my 289. Assembled.
However, my engine builder promptly threw out all the valvetrain parts and put his own in there. Along with porting and honing.

 

[RKS]

besides the Volks and tires, I spent way too much for this cat-back exhaust:
