What are the common troubles that afflict the BMW 323Ci?
With BMW 323Ci getting on in years, you can expect a few age-related troubles with this venerable model. For one thing, the cooling system will need checking—this includes the radiator, overflow tank, thermostat, and the like. You should keep an eye out for quick overheats and make sure to ask about the maintenance history if you're buying one used.
As it is a convertible, it's also common for problems to arise with the door. Some long time owners have also noted that windows on the older models tend to start operating slowly or making loud noises—indicating that the regulators are pretty much in their death throes.
How well does the BMW 323Ci's cover hold up after all these years?
The mechanisms that control the automated cover system hold up pretty well as it is very well engineered. Unless it is subjected to extreme stress—like operating it while moving—you can be sure that it will hold up over time. That said, it helps to have the canvas cover checked for degradation as the elements can do quite a number on it. This can be seen through fading, cracks, chipping, and other physical damage to it.
It also is worth bringing the mechanism up at the next maintenance check because convertibles aren't as common as other car types. This means that it can be glossed over and left out in the standard inspection and maintenance process.
Can I upgrade to bigger-rimmed wheels to improve the performance of the BMW 323Ci?
The truth is that the performance advantages of bigger rims have been long debated. The concept is simple enough. People believe that the reduction of components of the wheel that are merely just air can improve traction and stability. Aesthetically, however, it is beyond doubt that this kind of set up really does look better.
You have to take note of the limits within which you can expand the dimensions of your wheels, however. For the tires, you can work safely between diameters of 13.0" and 20.0"; while for rims, you have two range options. For bolt pattern 5x120, the diameter range is between 14.0" and 20.0". For bolt pattern 4x100, you can work between diameters of 13.0" and 15.0".
It's important to be extremely careful with the selection of tires and rims as this can affect performance severely when done wrong.
Is the BMW 323Ci open to aesthetic body modifications?
Like any car out there, customization options for the BMW 323Ci are many. You just need to look online to find a range of great kits available. A word of caution, though, make sure any bumper or side skirt modifications meet minimum clearances off the road or else you'll risk just damaging them as you drive along. What you should be especially watchful of is their clearances when it comes to speed bumps, which are often neglected by many owners at their own risk. Also, take into account the convertible nature of this care—certain tall spoilers might prove a danger to you and your passengers.
