Not always.
I plan on selling my 240 in a little less than two years.
Why? Because I can import an R32 fed legal then. My 240 has all name brand products, has a beautifully running Tomei internal'd SR, has a rebuilt transmission, Body painted CF hood, and a huge pile of mods. Power everything including steering. Interior is redone, dash uncracked, and the motor has been dyno'd over 400 wheel horse.
I'll put the car up for $5-6k and wait for it. Hell, id refuse sale to some kid with his dad's money. My 240 isnt 'someone else's problem that puts hurt on my wallet.'
I just wont need two '89 Nissans in the garage, and my Daily is a '98 GC8 2.5RS with only 50k miles. I have a tastefully modded complete car, that I will only sell because I'm done with it.
But, drift tax is a b****, my old rusted a** overheating 240 that i sold for $600 was resold to some kid for $1200 with just a new radiator in it. People SO over price these things.
