Upgrade from a 2012 318D to a previous generation 325 or newer.

Presently, I own a 2012 318D with around 145,000 miles on the odometer, and it continues to operate quite well. The problem is that I have had it for some years and need a device with more power.
I am considering selling it and exchanging it for a vehicle from around the year 2004 or later, namely a 325i or 330 model with less than 100,000 miles on it. Both options seem to have similar worth, so theoretically I would not have to pay any money upfront.

Will the older versions remain mechanically dependable if well-maintained, or will I just be acquiring a financial burden?

Any recommendations or past encounters would be very appreciated.

The E46 will be the chosen option. The engines in these vehicles are very dependable, but, the bodywork is now showing signs of deterioration. Rust is often seen in the wheel arches, door bottoms, and boot lip. Nevertheless, if you manage to discover a well-maintained vehicle and take excellent care of it, its value is beginning to appreciate due to its age, although by a small margin.

Is the wear mostly cosmetic, or will it result in a louder cockpit or any other related issues? Can I anticipate a significant improvement in performance when upgrading from a 318D to a 325i?

Thank you for your response, friend. I am not in a hurry to complete the exchange, so I will remain vigilant for a vehicle owned by an enthusiast, as per your recommendation.

I agree with the previous comment.
The automobile is excellent, albeit it is susceptible to corrosion.

Upon reviewing the MOT records for my last vehicle, a 21-year-old diesel 330d, I saw that it had failed due to issues with the rear subframe and other components. I sold the car six years ago when it had accumulated 157,000 miles.

What were the prevalent malfunctions of your device in the past? I am willing to tolerate minor repairs sometimes, but I really like to avoid frequent major infrastructure failures.

Replacing the doors, wings, boot, and other detachable parts affected by rust is a simple solution that just requires replacement and repainting. However, repairing the rear wheel arches and sills necessitates welding, and a high-quality repair work may be rather expensive. Therefore, it is advisable to steer clear of vehicles with these issues.
The power output of your existing vehicle is around 150 brake horsepower (bhp), whereas a 330i will have a power output of 240 bhp. Therefore, there will be a notable difference in power, as well as an increase in fuel consumption.

Understood, friend. I will postpone the concept for now, focusing on other tasks such as the wheel arch, and attempt to serendipitously locate a high-quality one. I value your counsel, my friend.

My E46 car had corrosion on the rear wheel arches, sills, and rear trunk.In addition, there were some minor improvements in various aspects. Both my e90 330d and e92 335d models performed well, surpassing the e46 type body of the previous e series.These may be acquired at a low cost, in fact, at a lower price than the 46 type body.
