You'll just love the R33 GT-R Chris
*The V-Spec has a quicker ATTESSA System to activate the front wheels.
*V-Spec is easily recognised by the fins on the rear diff.
*Besides checking for any rust (indicating that the car has lived much of its life near the Japanese coast or been driven on salted roads), do your usual checks as you would on any car.
*I would look for complete history from here as well as Japan &/or receipts.
*Wear and tear should be consistent with the odometer; including driving seat bolster, scratches on steering wheel as well as sun damage, scratches on ignition barrel, scratches under driver's door handle, scratches on door sill, gear knob condition (but that's often changed anyway), and ageing of the windscreen wiper arms.
*Electrics are usually good on the R33 GT-R.
*Brakes should be fine also, but need checking if tracked very much
*Do slow circles clockwise and anticlockwise with windows down to listen for CV clicking
*Check where the car is usually parked overnight to see if there are any oil drips. But put it up on a hoist anyway to check seepage
*Compression test is recommended
*Series II will have 2 airbags & later models may have Xenon headlights
*Don't be surprised about different quality rides in different GT-Rs since there is a wide variety of coilovers out there with different spring rates and settings
