Hi I'm new here and just have a couple of questions. I currently have a 98 Z28 M6 and it's millage is getting too high and small things are starting to go wrong here and there so I'm looking to get into a new vehicle. I have narrowed it down to LS2 GTO M6, a car which I'm familiar with and it's the safest option imo, The SRT-6 and 05+ G35 M6. I'm here because I'm not too familiar with the SRT-6.

I've read all the reviews and they appraise the performance, so that's obvious, at the same time I read the so-so interior, which is also ok with me because you can't get any more rock bottom than my 98 z28 interior lol

My question are the everyday daily driving behaviors. My Z28 on the highway can give me 24mpg, what's realistic to expect on this car?

Hows the interior room of this car? I'm not a huge person, but I'm not small ether, I'm 6 foot and 220lbs, my concern is that i'll feel really tight moving from the camaro to the Srt6, the No-2 back seats, i might get used to but not the fact if it's to tight on the width, would i be too close to my passenger, almost touching them?

Hows the reliability of this car? Any major issues or concerns that are known to go wrong? I'm not going to be racing this car, I just like to have a good looking fast car that my heavy right foot likes to play with sometimes, nothing too crazy though. I know it's a Mercedes underneath the hood so i assume the fixes aren't cheap, correct?

I've also heard it's actually quite manageable during snow time as long as you have snow tires, this true? this is surprising considering how low the srt-6 is lol

Thanks everyone
