Audi 100 C4 Review

A very nice little car. I've had it for over 3 years, so I can write a review. I swapped my Opel Omega for this Audi, even though the Omega was better maintained. The 'hundred' was very neglected, but in all this time, it only ended up on a tow truck once – the heater cracked, it was a cheap imitation, so no wonder. Nothing breaks in the car, things just wear out; replacements and repairs are simple, you can tinker, repair, and replace them yourself.

Pros: Reliable despite age, Simple to maintain and repair
Cons: Can be neglected, Wear and tear expected

100 c4

My first Audi. Quiet, quite sprightly, great road holding. Comfortable, beautiful interior. No idiotic add-ons like rain or dusk sensors etc. Ability to disable ABS. Beautiful, classic interior. Comfortable trunk with a practical underfloor storage compartment. Good visibility. Lots of space in the engine bay, easy access for timing belt and spark plug changes. The ability to set the hood vertically helps with car servicing. Pleasant, soft suspension.

Pros: Quiet and comfortable ride, Sprightly performance and great road holding, Beautiful, classic, and comfortable interior, Practical trunk with underfloor storage, Good visibility and easy engine access, Pleasant, soft suspension
Cons: Lack of modern convenience features like rain/dusk sensors

Audi 100 C4: Spacious Comfort for Those Feeling Cramped

If you're looking for a comfortable car and feel overwhelmed in a compact class vehicle, I recommend this one. Initially, I considered a BMW E34 520 or a Mercedes W124 2.6 cat, and mostly looked at those. At this price point, the Mercedes came with too much rust as a bonus, while the BMWs usually had exhaust pipes like a youth's weapon made of fence palings instead of a muffler and tinted windows (BMW - RURAL YOUTH'S RACING CAR), though some are genuinely well-maintained classics. When it comes to the Audi 100 C4, it's simply...

Pros: Spacious and comfortable, Good alternative to cramped compact cars, Better value than some competing luxury sedans at this price
Cons: Rust issues on some Mercedes of the era, Some BMWs of the era were modified aggressively

Audi 100 C4: A Timeless Classic

I've owned many cars, but this old, noble Audi stole my heart. It's my oldest car, yet I love it most of all. I was captivated by its simple design, durability, low-cost spare parts, comfort, and a style hard to find in newer vehicles. In a word, it's a car with soul. I acquired my 'hundred' by chance. I never liked Audi; it was too common for me. I always preferred older BMWs and Volvos. I also liked Fords.

Pros: Simple design, Durability, Affordable spare parts, Comfortable, Unique style
Cons: Might be perceived as too common by some

Audi 100 C4: A Gem for the Price

Bought for 3.6 thousand PLN. It's not a diamond among Audis, but for the price, it's a brilliant car. Super comfort, the automatic gearbox is a dream, shifts gears smoothly, almost imperceptibly. Kickdown is a bit slow to react, but once it kicks in, it's got some power. Fuel consumption is medium to high, I can't judge properly as the fuel float is broken and the gauge is always around 80. Minor issues like the central locking being temperamental – sometimes it works, sometimes it doesn't, and the ignition switch wiring.

Pros: Excellent comfort, Smooth automatic transmission, Brilliant value for money
Cons: Slow kickdown response, Unreliable central locking, Faulty fuel gauge sender
