340i47/70
The Deal
3
Book is 1.41 times the going rate for its power-to-weight, and the car loses about $2,565 a year, so the Deal comes out at 3.
The Drive
7
Electric steering like the 335i's, behind a B58 that reads as characterful, with its full 330 lb-ft from 1,380 rpm.
The Upkeep
6
Fuel at 25 mpg on premium and insurance near $2,000 are the two big lines. MoneyGeek's own 340i row reads $3,180, above the M340i's $2,808, so get a quote.
The Risk
7
Three of the four items are named in BMW's own bulletins for this car and years, and none costs more than $950.
The Daily
8
A five-seat sedan with a 17 cu ft trunk. CarPlay was a factory option from the 2017 model year, not standard.
The Limit
6
Competent rather than sharp: rear drive in a 3,695 lb sedan, classed F Street with the 335i and the G37, and no grip figure we could source.
The Mods
9
A flat $650 flash is tuner-reported at 360-410 whp depending on fuel, on an aftermarket shared across the B58 cars, and the extra boost leans on the same plastic parts the bulletins cover.
