Im looking for knowledgable opinions on these cars...we already own a 528i and I have an opportunity to purchase either of these cars for myself...the C320 is a 2001 and the 528i is a 2001...thanks in advance for any input
no its not a prestige thing....I have worked hard all my life and now I can finally afford to buy myself something nice for once instead of everything always going to the kids and hubby first..for once Im treating myself to something nice...

Ive driven the C class mercedes and am not at all impressed. It is a lower end mercedes, doesnt handle ir accelerate well and looks and is a lot cheaper than the bmw. Go with the BMW, hands down, without a doubt.

Worked hard for the privilege to own a vehicle in the class you are looking into. Initial intention was to buy a Mercedes. Test drove BM, Volvo, Audi, Jag and Merc. At the end it’s only personal taste. I enjoyed the Beemer`s cockpit layout as it`s shaped snug around the driver, the Merc was too open. (had the privilege to be the owner of 7 BMW`s over the last 5 years, 3, 5, 6 and 7 series) My 2002 5series was the pick of the bunch.
BUT both vehicles being 2001 models must be at the end of their motor/ maintenance plans, and might get extremely expensive to maintain if being bought for daily use. Price for example the respective replacement brake pads, a replacement gearbox, the exhaust systems. My advice to you, if you are still intent in buying such an "old" (old being at the end of the motor/ maintenance plan) luxury vehicle, is to buy what your heart tells you to buy. Both are excellent vehicles in different ways, it is up to your taste and need.

I have a 530i, the successor to the 528i but the same body style. The 530 was recognized by Consumer Reports as, "the best vehicle we have ever tested." At least as of 2003.
So I would lean towards the Bimmer but before anything, I would want to check Carfax and also see repair records done by the MB or BMW dealer. Also, take the car you like to a mechanic who can plug into the OBD2 port and get a diagnostic print out of the various mechanical systems. It's worth the money.

Totally different cars.

The C-class is entry level M-B for the US, while the 5-series is the mid-range BMW. Interior size will be a bit larger for the 528.

M-B uses a good 2.3L V6 engine while the BMW has an inline 6 cylinder 2.8L engine- about as smooth-running and bulletproof engine you will ever find. The Benz might have a slight advantage with gas mileage, but I can't comment on its reliability.

The BMW handling is legendary, with a nearly 50:50 front-back weight ratio for good balance.

Other things to consider are the mechanical condition of both cars, maintenance records, mileage, and how long you plan to keep it. I would say the BMW would have a higher resale than a C-class M-B.

I would go with the BMW, but then I am partial.

i like Mercedes better because they designed curvier...more of a woman's car.. BMW are too boxy looking for me

ps : the best ones are the JAGs

Honestly you don't need a detailed comparison here. Go for the Mercedes. I drove for some time CLK270 automatic, A200 auto, and a C220 manual. They all rock. Very reliable cars, powerful engines, comfy inside.
