Is it true that the last digit is on BMW is tell you how much the car cost is ex. 330i is $30,000

No it is not true.

The first number is the series of car, in this example the three series.

The last two digits used to give a clue as to the size of the engine. But this is no longer the case. For example a 328i has a 3.0 liter engine, but so does the 335i. The second one just has a twin turbo on the same size of engine.

The last letter means something too. You can probably get a list from some enthusiast web site.

Another thing to keep in mind with BMW is how much u can customize them. In fact BMW claim that there r over 130,000,000 possible configurations of their vehicles. So with that in mind there is a lot of price variance.

If u take a three series as u did in ur example, the current base price for a 328i is $32,700. But if u order it with most of the available options u can easily push the price to $50,000. The new one series 135i costs $36,275 but if u load it up with options u can be close to $48,000 for the same car.

With such a wide range of options & price differences, it would not make much sense to use the model number as a price indicator.

No l have a 535 ant it costs a hell of a lot more than 35k. The number goes by the engine.

It is supposed to refer to the size of the engine, ex. 330 is 3.0 L

NO HAS TO DO WITH THE MOTOR, ENGINE, POWER NOT THE PRICE, AND IT COSTS MORE THAN 30G'S

Nope.

The first number is model designation (3 for 3 series, etc.).

The next two r usually the engine size (30 for a 3.0L engine). But it is not always the case (like rounding a 4.4 L v8 up & calling it a 545i or 745i). Also, the new 3 series both have a 3.0L engine, but one is turbocharged (335i) & one is not (328i).

The l stands for fuel-injected, the type of fuel delivery system used in the engine. The diesel is use a d instead.

Also, xi denotes all-wheel drive, & l believe ci indicates convertible (or used to).

no, not true. The last numbers are the size of the engine. Except on the newer cars, for example, the 335i actually has a 3.0L engine. But on the older ones, it is accurate.
