I recently bought a pre-owned X1 E84 2012 model. I was lucky enough to get one with the sunroof.
I made the mistake of not getting a qualified enough mechanic to verify the purchase, hence had a demanding few months before I could get the beemer into proper action.
Issues Faced:
EGR valve was jammed completely, while I took it out on my first long drive. Spent some money on getting the car back to Bangalore.
AC compressor and condenser replaced.
Radiator hose gave up, thankfully, while at my new garage.
Blower assembly was a mess, flap motors were missing. Had to source the entire assembly from Delhi.
ABS module error - still no fix found, no issue with the brakes or sensors though.
Fuel injectors had to be serviced and injector pins replaced.
Pulley bearing, pulley belt, Dynamo bushes, water pump were the other replacements.
The total expenses were around 1.5L.
Reasons for Buying:
This was/is my first German car. I still have my dad's Zen 2003 model, which is in pristine condition.
The reason I zeroed in on the X1 were pretty common(I think

). Bmw is known for making driver oriented cars. Hence the brand was a no-brainer for me.
Next, I wanted a crossover, as they're definitely more frugal than SUVs, and have the bare ground clearance needed to survive in the near roadless conditions of Bangalore (no offence to Bangaloreans).
I needed a point and go car, meaning the car should think and behave like me, no questions asked. I have a heavy right foot, and that is a death wish if the machine will not co-operate.
Automatic is a need to have in our traffic conditions, but considering this would primarily be my long drive car, it was not a necessity for me.
Experience:
The car is nothing short of excitement redefined, unless you're used to driving anything bigger, like a 3.0L turbo diesel, naturally aspirated V6 etc.
Although this particular model comes with a ZF 6 auto transmission, I find it quite responsive and not lagging at all, although a ZF8 would definitely be better, which is available on post 2013 models.
I am used to driving 6-10 hours straight, all the way from the winding roads in Kerala, to the near straight highways from Madurai to Salem, to the ghat sections post that route as well, till Bangalore.
The seating position is good for a 5'5" guy like me, so not sure if taller guys would have a similar experience. I have not faced any comfort issues so far, although I don't think that would be a criteria for you, considering your usage.
I usually cruise between 120 -140kmph, occassionally crossing that if our roads and sensible highway riders permit

. Please note in no way am I endorsing exceeding legal speed limits. They're there for a reason, and should be abided by all.
The braking and handling is too good. I have had instances where jaywalkers have popped out of nowhere, at night, and all I have to do is kiss the brakes and caress the steering accordingly. No drama there, the car shows the difference between German engineering and ROW.
The luggage space is decent enough (creta can be used as a reference).
The only pain point is sourcing the parts, like some experienced BHPians have already mentioned in the thread.
If you can deal with that, and the fact that a sunroof model is rarely available in the used market, then I would definitely recommend the X1 E84.
Please ensure you've a qualified mechanic, with a scanner, to thoroughly check out for any unwanted surprises. Do remember that more than your willingness to deepen your pockets, is the availability of the spares. My new mechanic (thankfully a man who knows his job) is still of the opinion that I push the car at a good price, although being the person that I am, I won't
I do have a query though, is anyone aware of examples of tuned X1s ?
