Having driven both (including a 155Q4 and 156 GTA), it is a complex matrix based on which version and condition these days. Personally I feel that the 155 V6 is utterly lovely and great if you do not require max progress. It sounds great, handles well (if in good nick), and can be easy to maintain if you are handy or have an Alfa mechanic nearby.
The 156 is a massive step up in design. However it uses even more plastics and sensors. And the electronics are both a boon and curse. But this is with hindsight. At the time this was a ground breaking car not just for Alfa, but all smaller production manufacturers.
1·11 months ago- It looks nothing like a Corolla or any other eco-box of the time.
- It’s arguably the most special feeling FWD sedan/wagon of the class in its era and the Busso has a glorious soundtrack.
- Considering the money asked for a 156 GTA today, you have to be an aficionado to buy it. For everyone else: just buy an E46. Much better driving car, much better car in general.
