I spent the afternoon with the Renntech guys - I followed their modified SL55 across town (I felt very insignificant by comparison in my 32) - the 55 was by far the nicest looking car on the road - it looks very sweet from the rear! They've also modified the interior with carbon fiber, new springs and wheels, larger engine, etc. I'm kicking myself for not bringing a camera. I heard that car and driver tested this car and it will be written up in the Sept issue (along with the SLK38).<br> <br> I also got to test drive the SLK32 with the stage 1 enhancements. (I'm bringing mine in later this week for the stage 1 (ECU and pulley upgrade) and new springs) The car had quite a bit of kick to it - and very smooth. I can't wait to get mine done!
