Depends on what you want.
If you want raw power, aggresive looks, go the R32 GTR....
BUT....u need spare money, stuff breaks, and by the time its running 100% u'll have had spent a fair bit extra.
If u want realiability and a newer car, then def. go a s2 R33. Nice, reliable, enough power, only downside it is perhaps THE most common import along with s13s. Plus it won't blow ur budget, they are relatively cheap to maintain, when compared to a GTR
Yes a GTR is a GTR......but the expenses don't stop once u hand over the cash, it's an ongoing expense.
