i may be interested in this, is it £20 for the rollers?
Yup, £20 for the rollers and you'll get a number of power runs; until either it's obvious we've hit a peak, or until your engine blows up*

If you want to stick your name down send me a PM and i'll give you all the details that you need

* Obviously I'm joking! Your car will be treated like a baby unless instructed otherwise by yourself!
