What used BMW 3 Series hatchback will I get for my budget?
How much does it cost to run a BMW 3 Series hatchback?
Anything with a BMW badge does not get sold cheaply and that rule applies here. This is far from the cheapest small hatchback.
Insurance costs on the 316ti and 318ti are reasonable. Provided you don't succumb to the lure of a Sport badge, you'll face no more than group 12 costs. The diesel variant sits one group higher, while the most costly to insure is the 325ti, in group 16.
The 325ti is also the thirstiest model in the range, retuning no more than 31mpg on average. The 316ti delivers a claimed 40mpg, although the more powerful 318ti almost matches that with 38mpg. Most economical of all is the diesel, at a claimed 49mpg, which will still easily translate into 42mpg in the real world.
Servicing is required every 15,000 miles, but BMW dealers are far from cheap, so unless you are buying a very late car with some warranty left, it makes more sense to seek out a good independent specialist.
