Love the car, I have a couple regular 2.3 190e's. I just enjoy driving them, I have had 2 E30 M3's and sold them before they became unabtanium . I keep looking at the 190e 16v's but worry about the reliability of them. I have had quite a few issues with my standard cars. The fuel systems and so many other sensor issues, I wonder if the 16v may be a bit easier to deal with? I have even considered going to a different fuel management system on my 2.3. I have not found another car that I enjoy driving as much as the baby benz, even have a Porsche 911sc and I would drive the merc every time over the Porsche, it's just fun to drive. I just wish they were easier to work on and track down problems. Love your car, and will be watching the build. If I had anything even remotely intelligent to add about your SLS system I would, but alas I know nothing other than it looks to be a pain in the rear. If you have time I would really like to see pics of your other 2 cars as well.
