Hello all, been a while since i posted on here since selling my old 318i! (moving house = need money

)
Well im now in a position to buy another one, and this time im gonna go for a 6 pot, more than likely a 325i (to avoid the nikasil problem on the 328i/323i engines in the UK)
What im asking is, as i cant seem to find the right info anywhere for UK models, is there any difference between the engines from 92 to 96? (i read somewhere that until late 93 the 325i engines didnt have VANOS, whether thats for UK or USA or not i dont know)
Also is there anything specific to the 325i that should be looked at while inspecting the car before purchase? (or is there anything specific to the 325i that goes wrong other than the usual suspects, ball joints yada yada)
Hope someone can help as you often did before!
Clint
