So which did I go for in the end? This:


316i, (1.8 engine) so the baby of the range. I had a 316 E30 years ago which swayed it.
I decided against the V40 for three reasons, it would have to be an LPG version and the tank on those is nearly as teeny as the in the V70. I'd probably have been filling up around the 250-270 miles mark vs 220-240 in the V70 but that's still twice a week. V40s rust a lot more than a 70. Lastly the V70 and Mundano estate I had on hire would only just turn on my drive in a single shunt. A V40 is only better by a foot.
I decided against the Jag for two of the same reasons, turning and the tank. A very nice 4wd ready converted to LPG came up but the range would be between the two Volvos. A converted 2wd would be about the same as the V40.
The reasons I went for the BM are:
Correct wheel drive. I hadn't thought of that but when I realised I did rather latch on to it.
It's already cheap enough on fuel without a conversion, 39 mpg last week and 41 this.
It has an absolute cavern under the boot floor, I've not checked yet the range an LPG tank in there would give but I'm guessing just north of 300.
Correct wheel drive
Related to the correct wheels being driven it has a vastly better turning circle.
Cheaper tax
No cam belt
It's a colour. Volvos don't come in colour and X-Types are rare. The 4WD I liked was a green I could certainly have lived with.
It felt at first under powered and a slug, I don't care and got it anyway. After two weeks with it I've found that if you get the revs up it really does go quite well. It handles like a car rather than an oil tanker. It's much smaller than the V70 and although I did use the space it wasn't that often I rammed it full. So far I like it. I may convert it to LPG but not immediately, LPG has only fallen 4p so the payback time on a conversion is increased just at the moment. The price should fall more even if oil and petrol go no further.
I'm still waiting for a refund from the insurance for the car I hired myself (sent out once with the wrong name on the cheque) but the payouts for the car exceeded what I paid for it and bought the BMW plus 6 months tax.
