What are the differences in BMW models.?

I had this same problem. My budget assured me I could get a used BMW in the 3-series.

My mechanic, who is familiar with my driving - suggested I get a 330i. (x is for 4-wheel drive - like the 328xi and a 330ci would refer to a 2-door coupe - and a 330cic refers to a 2-door convertible). The 325 was cheaper - and one friend suggested I save a few thousand. Though they both have 6 cylinder engines - they are configured differently. The 330 has more power and better gas mileage (the faster I go the more miles per gallon I get!).

I asked about M-3 and M-5s. I was told literally to forget it. If they ever came off warrantee I wouldn't be able to afford maintenance.

I asked about Series 5 cars - the 525 and the 530 - and it was explained to me they have the same engines as the 325 and the 330 - just a bigger, roomier car...

I just saw the new 335i the other day - it's a turbo - beautiful -- but not in my budget.

Over the summer from a BMW dealership, I found the car I was looking for. A 2003 BMW 330i in Steel Blue Metallic and every option conceivable (including the sports seats and wheels). It came with an extended warrantee and I paid a little extra to take care of brake pads, rotors, oil changes, etc. until January 2009 or 100,000 miles which ever comes first. Which, if you are buying - you may want to consider doing.

Needless to say, I love the car. Now if I can get my husband to stop using it as his daily driver... LOL

Size and price are the main factors. The Z cars are the 2-seat convertibles. The numbered cars get bigger, more optioned, and more expensive as you go up. In general, the 3 series is about the size of an Accord or Camry. The 7 series are more like your Lexus/Infinity cars. Lower than a 3 series is your smaller car, like a Civic. Within each series, there are different numbers (320, 328, etc.) As those numbers go up, generally you get more options. Lastly there are the M cars which stands for "Motorsport." That's the go-fast version of that series (the M3 is the fast/performance version of the 3-series cars).

the x models are suv like X5 and X3

CARS- the 3 series are the best seller

323i 325i 330i M3 - 2 and 4 door $33,000- $50,000 (and c means convert.)

(the M3 has about the same performance as a vet)

5 series- 4 door

540i 545i M5 (507 HP) $45,000- $75,000

7 series- large 4 door

735i 745i $75000 and up

They have different packages like sport (upgrades seats, suspension, and some other features) and premium (upgraded interior). Best thing your could do would be to go to the website and do a build your own. It explains the packages during that process.

There is no difference...they are all expensive pieces of s h i t !!!
