looking for some grunt.anyone owned any of above.any opinions.

 

My money would be going on the SL55, a mate of mine has had a couple of them, SL65 is the way to go though

 

SL 55, all the way, sound awsome.

I was i a slightly tweeked one and all i can say is wow.

 

RS6 does seem to suffer with suspension issues. Not sure what the SL55 is like but the 2 cars are very different so if you don't need the practicality of the Audi go for the Merc

 

Neither. Buy a 911 Turbo for thrust and reliability.

 

Isn't the SL55 just a 2 seater?

While the RS6 can carry you, wife, 3 kids, luggage, and a dog.

If it's just a 2 seater you're after, 911 Turbo every time.

 

you wont lose as much cash whilst its sat in you're garage either

 

Chap near me owned an old school RS6 ... sounded mental on take off!

TX.

 

Defo SL55 ..niiiiice!!!

 

Both amazing animals in their own right and far to hard to compare. Have driven a number of SL55's in my time and they never fail to put a smile on my face.
I think the practical person in me end up having the RS6 just as it can do everything you would want and take the kitchen sink to the dump on Sunday.
