E30 (1982 - 1993)
God's Chariot. The E30 was produced primarily from 1982 through 1991. The cabriolet was the one exception which was produced through 1993.

What's the difference?

so I have a '89 325i and at school I've noticed a few other people have E30s as well but I've noticed on theirs they have 318i and other numbers, is there a difference?

Yes there is a difference. As far as I know, the 318i has a different engine. The 318i has a 1.8L Inline-4 engine (M42). The BMW you have has a 2.5L Inline-6 engine (M20). Other than than the difference in engines, their pretty much the same cars, although the 325 may have some more refinements than the 318i

Mein Auto: '90 325iC
Example:
BMW 325ix
3 = series (3 series)
25 = engine displacement (2.5L)
x = AWD

So a 318i would be a 3 series 1.8L engine.

I do not know about the USA models but Europe and SA models the 325i has disk brakes at the rear and beefier suspension while the 318i (all years) has drums at the rear....318i in Europe and SA also generally has the 8 valve M40 1.8 engine with timing belt while the 16 valve M42 has much better performance and uses a timing chain...a common engine upgrade here for the M40.

what about 325e or 325? those had 2.7l heads

number are the series, letters are trim options. dromey is basically spot on, there are a few exceptions as i pointed out. think of the series being the size of the car. at the time, 3 series were the smallest in size as the 7 series was the biggest. the trim letters are the main packages available. so "i" and "e" are your base model, "is" and "es" are sport trim, and "ix" is awd.
