The B200 and B230 were both produced at the same time. The only
difference is the B200 has smaller pistons and a 2.0 litre displacement
vs. 2.3 for the B230. And Volvo's naming does not always work on the
middle digit, there are some x4x (mostly diesel) cars with 6 cylinder
engines, and some x6x cars (primarily turbo) with 4 cylinder engines.
The first digit denotes the car series, and the last is either a generic
"0" or the number of doors.
