problem with the 3 series is insurance, for me anyway the 525 is about the same as what a 318 would cost to insure. how the fook insurance companies work out they're pricing i will never know.
what kind of miles are these good for? as theres loads around in the 100-130k bracket, are these likely to be completely tired and fecked or is it worth paying the extra and getting one with 80k on the clock?
