So I'm selling my CLK55 AMG as my other half is allowing me to have one more nice car. The question is whether to got for either of the above. The Audi is winning at the moment based on 4 wheel drive being new to me, slightly better performance than my current car, good boot space and goodies that are key to me: satnav, adaptive cruise control and keyless go. Funnily enough MB Bromley have told me that keyless go is not available on any C class coupe save for the AMG. Anyone on here have experience of the current Audi S5?
