Sorry guys and gals to be a pain but am struggling to decide on whether to buy early or a later car. Normal head says as new as possible but currently stuck between deciding to push the budget to the absolute max of £25k and seen a very specced 20d 2019 for that or 2017 with a few necessities for £7-£8k less. I can't decide if I might feel I've made the wrong choice if I go early/older or sensible that I'll have not spent a chunk of money. The car will have to last quite some time.  Went to see a 20d this morning and ended up driving an X4 M sport.  Nice car but the suspension was just too hard by contrast the X1 mSport I then took out was a lot nicer, 

Morning Richard

Car change time always difficult 

First try as many as you can (extended test drive if possible) so you have a good comparison. The car condition and history are paramount don't just look at it check it online.

If BMW is your choice, buying from a BMW Dealer will give some comfort as the car should come with an AUC Warranty. If buying from a Non BMW Dealer it may be worth paying for an AA/RAC report on the car and insisting on a Warranty (make sure it is in the sale price not and extra) My personal preference is as many bells and whistles as possible apart from a Sun Roof when you have AC/Climate control I don't see the point.

If buying privately then you will be largely on your own so making all sensible checks would be essential
