I don't ever regret buying my 2004 Roadster new. I like the way it revs - none of this 'put in top gear and drive it all day'. If that's what you want buy a Mercedes convertible.
Yes it don't sound sexy but they made it quiet so you can hear the +8s trying to keep up

And yes, I've driven lots of +8s and Aeros including a GTN.
One man's meat ...
