New purchase - Advice

I've had my M40i for nearly two years, it's been a most enjoyable, comfortable, relaxing and highly entertaining 30,467 miles. As a daily it's practical, economical and easy to drive. As a sports car the B58 is sublime with endless torque and super smooth, overtaking is a breeze. Lateral grip is immense, which is both good and not so good, as there's no slippage at legal speeds, the electric steering I would say is my only real criticism.

Just fitted the winter wheels shod in all season Conti's, with these on the car is great on frosty mornings or a few inches of snow. The Michelin Pilot super sports are not great when cold.

Thanks for all your thoughts I’ve already test driven the 255bhp - 2litre
There’s also a 195bhp same money - but just has all Tech packs

My other dilemma is having always had 6cylinder Beamers - is it worth saving & and or adding too - and getting the M40i

Are there big differences - other than the obvious £4/5k additional cost ?

I've only driven the M40i but from what I've read in other forums it's a very different beast (in a good way) to the 4 cylinder versions. If you can afford it go for it !
 
I've owned my m40i for 2.5 years. I've done about 18k miles, ~10 trackdays, 1 NC500, two snowdonia (North Wales), multiple peak district, yorkshire moor and dale trips. In the past two months, weekly trip between Sheffield and Cambridge. Overall, very enjoyable experience so far for my use case. If you pick any one aspect, G29 is definitely not the best. But if you combine all of above together, the result is that I can comfortably (not as comfort as my G31) cruise at 70mph and achieve ~50mpg (not as eco as my G31) on the M1 to silverstone to enjoy a day of fun on track (my G31 can't even compete on this at all, but I agree that Boxter might be more fun here) and come home comfortably, then take my son with all the luggage to do NC500 with roof down during the summer holiday.

If you have the budget, go for m40i to enjoy the straight 6 as an extra bonus. But if not, B48 won't let you down.
If you ask package, well, mine only has comfort pack. Nothing else. I still enjoy it so much. But again, if budget allows, tick everything.
 
Once again appreciate your real life ownership experience , as my family are now all driving themselves my X6 as much as I have loved it is ready to be changed and for me the G29 seems to be the way to go .

A rear-wheel drive sports car is great in the Summer but a liability in the Winter. Also of no use to carry anything to the dump!

Unless you're the wife and drive Z4 as a daily. I would say G29 is pretty good daily. You can bring decent shopping home and even christmas tree. I even bought rolled grass once and brought it in the boot.

It's quiet on motorway, 2.0l engine is more efficient than expected. I did around 19K miles in less than 2 years in it and half of it was abroad.

Fab photo - for my budget choice of two both same price , both sapphire black & red leathers , m pack on both - the 194 bhp has all the additional packs - the 254 bhp No heads up or Harmon ?

What to do ?
 
Really subjective choice on what packs you consider essential. For me it was the comfort and technical packs, and that's all I've ended up with. Specifically the wind deflector, heated steering wheel and HUD were my deal breakers.

I would say the wind deflector is the key thing to have regardless, but can be fitted after purchase. The parts for it used to cost just under £500, not sure of current prices.

Unless it's raining than you'll look a right muppet. :fuelfire:

That's what my 3 Series is for!

Anyway OP I wonder if the power difference is just a map? If so I'd chose the better spec with less power, but if not I'd chose power first as options can often be retro-fitted - unless you think either is essential.

The 30i is a remapped version of the 20i..so out of warranty time then... :driving: :driving: :thumbsup: :tumbleweed:
 
Great info as ever- I did wonder wether a remap would be the way to go - essentially it’s the same engine and although the two am loooking at the194 bhp has also 10k miles on the clock both are 2020 year . Could you recommend anyone in Lancashire who carries out the remaps ? And any drawbacks

Given the purchase price I’d recommend a trip to some one with a strong track record and someone who can dyno it before and after…

I use some guys in Sunderland that I’ve had lots of tuning done with..I’m sure there are folks closer..

The B48 engine is a great design learning from the N54/N55 so is well capable of around 300 BHP ..up from the 180 BHP ish on the 20i and 250 ish on the 30i

The gearbox may need its TCU mappimg to suit..again a tier 1 shop should know what they are doing..
 
I got my new G29 2 months ago, 20i which has enough grunt for me :D

I went for Sapphire Black with Ivory interior, sounds a bit bling but looks stunning. I have witnessed several occasions where people have been photographing it on their phones, including today on Sainsbury’s car park!

As far as additional packs, I went just for tech, which gives you HUD, HK sound system, parking assistant (including rear view camera), good value for money compared to other packs IMO but each to their own :D
 
The lower powered B48 engines in other installations have different pistons / internals than the higher power variants and some have had piston issues when mapped, so be careful if going that route. No doubt the G29 is the same, but check on realoem to be sure.
