Thinking of a change!

But what to buy?



Cash/PCP/Lease?



I'm tempted by an M135i - drive the deal are doing £6.5k off list in the spec I want..



But then I'd love an M235i - but the deals ain't so good and the finance is higher apr.



Also considering a BMW 550i - 4.4l twin turbo v8. But then I'll be in a 3yo car..



M3/RS4/C63 - 5 years old - are these a big risk?



A warranty seems appealing..
