So we have already solved the problem your freind got a
sentra! That white car is a 240SX in the US and in Europe or Australia/New Zealand they call it a 200SX and in Japan it's a S14 but that with the names is a long story maybe you go check the
Sentra forum.
The Sentra is not comparable to the Silvia (S10 to S15) cars. It has completly other engines and quite no similarities to the Silvias which are real sport-cars.
