16v = 150bhp
Vr6 = 174bhp
The 16v is easily tuned up to around the standard figure of the vr6.
The Vr6 is reportedly a bit more tempremental. Prone to head gaskets.
But the Vr6 is not just a cruiser!
The best model to go for is the Vr6 Highline.
If you decide on the 16v then get one with as many toys as possible, air-con/leather etc.
