I thought since I have posted so many negative items lately, mostly regarding the 2005 command, that perhaps I should share a positive experience I have recently had with my car. I don't know, maybee it's just me, but I do get a tickle out of the tremendous power this RENNtech SL600 has. Today on my way to work I was tooling along at about 70mph when I just decided to poke the accelerator a bit. Well let me tell you, I barely poked it and I was burning all kinds of rubber. Why, I could have burned the tires right off the wheels if I wanted to. That's right, burning the rubber "off" the wheels with a "touch" at "70" mph!!! Don't get me wrong, I'm really not a tire-burning kinda' guy. But the power this car has after my upgrade is nothing short of astonishing!! I have had many high preformance cars but none, and I mean "none" could hold a candle to this thing. The acceleration on this car is visciously fast yet smooth as silk. Totally controllable at all times but believe me, the accelerator is always treated with great respect. Any of you out there with SL600's should consider the upgrades. They are truely a value considering the tremendous improvements to HP and torque. I just love this RENNTech rocket-power!!!
