Rare Matrix XRS with high performance engine. The only auto engines as far as I know ever sold in the US not named Ferrari that make 100HP/Liter without forced induction. It’s more like a 4cyl motorcycle engine. The engine runs perfectly and spins happily right up to redline. I don't venture there for long as the miles are getting up there butthe fun of this car is to hear the sound as the high lift kicks in at 6200rpm. It wails. It will happily putter around at 2000 rpm in 6th,just don't expect it to accelerate from there.
