hey mate,
Thats my 33 GTR in your link. 3 years ago i went through the same thought pattern as you.
Loved the 34 gtr, took one for a drive and yep good. standard, with normal bolt ons, non Vspec $70k.
Decided to go have a look at the 33 GTR Vspec (that i bought), forged engine, plenty of mods, well kept, plenty of power, drove it and it felt like a different beast. $30K
Couldnt justify spending $40K more on a car i knew i would put more money into when the 33 had all the go i would ever need. Plus if anything went wrong, the price to fix was large
Dont regret buying it to this day and will be sad to see it go out the door when i find a buyer for it.
