That 6 is nice! Struggling to think why you went with a 235i to begin with?!
At the time the options on the table, and to be honest what I wanted, didn't bring the 640d into my budget. I also really liked how the M235i drove, and still do, just the range of problems I experienced put me off ordering another one.
I had ordered a 335d which if they'd delivered it in the time frames originally discussed I'd have gone for, but again circumstances transpired to mean that it wouldn't be delivered until sometime after March 2015 which when I was ordering it to replace a car due to problems seemed to be a bit of a long wait.
Whilst looking at other options with the Business Manager we had a look at a used 640d they had just taken in., which i liked it quite a lot so he ran some numbers which looked promising. I asked about an extended test drive of that car but because it was untaxed they couldn't do that, so they lent me their 14 plate MY14 car for a couple of days. I loved the way it drove and how it felt to be in it, so spoke to him when I got home about the used car, at which point he said he'd been playing with the numbers on a new car, and if I could put in a bit of a deposit I could have a new one within my budget.
Became a bit of a non-decision then, as whilst its costing me more through the deposit and monthlies than the used car, the net effect once you take into account servicing, extended warranty, extending the online services and the fact the used car had the older wheel and satnav the overall cost through the time I'll own it isn't that much different. So I bought the new one, which I love...
