The v8 can sound quite close I think abeit not as high reving as a petrol, I got my exhaust pretty close to these examples

The v10 stock exhaust though that would be a selling point for me I think, plus the slighty better interiors in the 'S's. I'm full time working from home so 15k miles a year to around 2k I could justify the petrol
