I test drove the S4 twice.
- Felt heavier, bigger, less nimble
- MUCH more expensive lease payment. Residual was not as good as BMW.
- (opinion) F30 looks better inside and out
- That silver painted plastic around the instrument cluster was a huge turnoff, looks cheap
- S4 body style is OLD now. Likely to get a complete overhaul before the end of a lease, rather get the all new look of the BMW.
