Looking to downgrade or is it upgrade my 120D M Sport Coupe

[LGriffiths88]

evening all

So I need to shift my current 120d coupe as its too small for my family needs. Need a 4 door motor now to help get the kids in and out with ease.

Looking for a petrol as I have no need for diesel now due to moving closer to home for the family. Wife has mondeo diesel should I need it for work. My current diesel has given me no end of hell (egr valve, causing loss of full power for acronyms 15min until it clears (anyone else had this issue))

Is it worth looking at those BM diesels.

Here's what I've thought of, ideally in sport/m sport, do like the estates of both too

E39 520 to 530i.
E46 320 to 330i
Outside choice - 7 series
E60 m sport
E90 m sport


I have a budget of around £5k. The last 2 cars I imagine are out of budget. Are close to 100k 3 litre engines reliable enough. How do those engines sound? Would they be the same as my previous 04 reg 2.5 z4? Can't remember which n engine it was.


Need to fit kids in back with ease including baby seat
Percent boot to fit pushchair/double one
Reliable
Parking sensors

Cheers
