Thanks Javier. We have our eyes on the D250 as our current Discovery 4 is 255bhp and seems to cope well with towing our horses - we cannot go too fast with them aboard!. My aged parents have told us that they much prefer riding in our Discovery 4 as opposed to our Mini Clubman. The 50mm lowered Discovery is easier for them to get into than the very low Mini.
Hello again Paul! Between the D250 and the D300 I guess you won't feel much difference. These engines are about torque, and the D250 has already plenty of it. So, as you say, it might be the wisest option.
If you accept my suggestions, please note an option that is, in my honest opinion, mandatory: the MATRIX Led headlamps. They are impressive! A huge difference. In Spain they come with the HSE level (or some of the upgraded models). And also highly recommended the big 11,4" touchscreen.
