The R33 can be converted for $25K, and a whole car from Motorex for a 97 is $61-$63 depending on the model (GT-S, GT-R, V-Spec II, in that order) so the price is comparable and could be even better if you find a good one on your own for the right price, and the RB26DETT is well known for being bomb proof, able to hand 500+ hp with ease, so maintenance shouldn't be that big of a deal, the only issue I could think of is the ATTESA 4WD system could get pricy if problems arise. I know one of the top mechanics at Infiniti Mission Viejo, who worked on the police’s R34 demonstrator, (I think he said it was their D.A.R.E. car for kids, makes me want to be a cop to get that job :biggrin
but he said that general servicing isn't that much at all, and can be done if the right person is found.
Now on the issue on what to get, well my philosophy on cars has always been 'to each their own' but on pure looks has to be the NSX hands down, but performance and rarity the R33. Also I somewhat like the stealth aspect of the R33, not everyone knows what it is except car nuts, so you won't attrack attention, but most cops do know what they are because of street racing so that may be a problem, just ask
prova4re and the Mischief V Dynasty crew.
