You think it would be a good idea for me to get a warranty on mine? '04, low mileage, very good nick... (until I started driving it

but luckily i've got a good warranty
Would you say in retrospect you might have been better running a ci petrol?
Which kind e46 are you looking for? A powerful one? An economical one or a cheap one?
For example you could pickup an 318i in Sport or SE form. Won't set the world on fire but enough power to live with. Also it's cheaper to run and buy.
I think the general view is that, whilst a warranty gives good piece of mind, it is better to put say £600 a year in a savings account to cover issues with the car. I think most people find that over the course of 5 years there'll be (at least a little) cash left in the account.
Fox, how much did you pay for your 530i?
