The 3.0 coupe is 261hp and 0-60 of 5.5. I think you might be looking at the early 3.0 roadsters. Still, performance wise it would never keep up with my old VXT I know but I was just wondering if the 'real world' differences between the 3.0 and the M were really worth the extra costs (which from what I can make out, are quite substantial!)?
Stage 2 VX SC is on a par with the Z4M I had. M would be quicker in a straight line and at 100mph I think it would noticeably pull away. On smaller tighter stuff the VX would prob pull away. Wouldn't be much in it though tbh.
3.0l is meant to be the pick of the bunch and I've heard from people who have owned both that the extra costs don't give you the same bang for buck in the M. I drove both back to back and bought the M as it was an animal in comparision to the 'sporty' 3.0l.
£950 insurance/£800 a set of tyres/ £500 a yr tax got boring quite quickly for a car that was a bit heavy and expensive to track.
It would have made a great second car if I was 'considerably' more well off.
