Diesel v Petrol on X Models, am I making sense

[Smuler]

I'm in the market for a small (ish) SUV.

I'll use the X1 as an example. It will be new, or very nearly new.

What matters to me is :-

1. Lowest running costs
2. Lowest depreciation.
3. Easiest resale.

What is of less concern is the initial purchase price.

It will be a cash purchase.

Of the two competing M Sport 20litre models, the above criteria suggests that the diesel is the better purchase.

Agree, disagree, anything I should be aware of?

The journeys will mostly be 30 mile round trips or 90 mile round trips. Car used at least 6 days a week. Annual mileage 15-20,000

Thanks, as always.
PS the M3 is staying, I'm not considering a total shift to the dark side

Thanks for the responses, have arranged a test drive of a diesel 20d
I drive what I believe is the petrol engine in a 220i Active Tourer; nothing special so I think for this sort of thing the diesel does make sense.

For those who may be interested I enjoyed my test drive and liked the diesel engine with the auto and bear in mind N/A manual is my preference, so I'm out of my comfort zone.

I found it responded better than the 20l turbo petrol which is I think supposed to be faster.

So all things considered for this kind of car, certainly with my mileage, I think the diesel is best.

Thanks again to those who commented on my first post.

I always like it when threads, asking for advice, are concluded; so not to be a hypocrite:-

I went for the diesel. I preferred the engine, felt it was smoother and picked up better. I did briefly consider the more powerful 25d but won't be driving this vehicle on for example long demanding, motorway journeys where I might want that extra, extra surge and although I'm impressed with this X1's handling and ride, I'm hardly going to take it on a b road blast as I do the M3, so I really wouldn't get the value.

Thanks a lot to this forum I've learnt about Broadspeed, Coast to Coast and TRL. I got their best quotes and found a local dealer to beat that price, to the extent of 10% of their discount.

Options I considered but discounted, pano sunroof seemed a nice idea but really expensive and the excellent visibility in the X1 gave plenty of light even considering my two test drives were in vehicles with the horrible privacy glass.
Reversing camera, I'd been recommended but I found too much information and a bit confusing, rear visibility is good and parking sensors with graphics is sufficient.

I went for driver comfort pack, because I did fancy the front parking sensors.
Folding mirrors because I drive down such tight streets, it's really handy
Lumbar support and elect adjustable seats, bad back meaning extra support and because I like to make minor adjustments to driving position on the go.
Sport Auto, as discussed so many times here, it really suits the engine and the sort of driving I'll do in the X1.
I hated RFTs in my 335i, so going non RFTs added space saver, as I won't use that much of the storage space, so it can use up the underfloor storage
Finally, as it was only 150£ I went for EDC a bit of a punt but it supposedly sharpens things up; though I did feel there was more weight with the standard steering than I'd found on other similar BMWs

Car is the M Sport so anything else I wanted was standard.

Thanks again.
