You'll find that both stock standard the cars are very different, the Skyline on one hand, is very refined, fast point-to-point for a standard car, is a car that inspires confidence to drive quickly and will grow on you day after day making you feel like you owe it to the car to modify and upgrade it's performance. The Silvia on the other hand, does in fact feel like a teenagers car, it can be very harsh in ride quality, is noisy and is far lesser of a car (standard). But what I'm trying to put across is, you cannot compare a five year older, less performance delivering car to one that is far better in every aspect, but FOR THE SAME MONEY! You could have blown your bank on a standard car that you still love to drive, but say you have bought a Silvia for $10k, you still have $25-$30,000 left to spend on your Silvia that can fix such things as performance, ride quality, day to day drivability etc until it becomes a better car than the Skyline for near the same or less money.
