Build your own Ultima
I REALLY don't think you have any idea how utterly SHITE Nobles are.... I used to LOVE them and even considered one as they are blindingly quick on track out of the box. (Shame they don't have sump baffles as standard... so even a moderately quick driver WILL fuck the engine on track!!)
I know 3 people that have owned Nobles. One of them said it made his TVR Tuscan seem well built, well designed and reliable.... now THATS scary....
