I had an 01 E200Kompressor Avantgarde as my last car. I kept it for 18 months, and can tell you the following.
1. Being an Avantgarde, it was a 2.0 supercharged, and had 165bhp.
2. It was automatic (the only way to go, btw.........)
3. Light on fuel. Normal school run averaged 28mpg (3 miles each way). Take it on a spin - Galway/Limerick could get 35mpg easily. Very impressive. And I'm mean, believe me !!
4. Had 1 problem - a bearing on superchager belt tensioner got a tiny bit noisy, so they changed it, ..............easy and quick job, and I was being pedantic anyway........
5. Highly recommended !
6. Cheap to buy, secondhand (an awful lot of them for sale, secondhand - buyers' market)
7. Cheap to service.
I'd imagine in the smaller car, that performance should be at least on par, if not better.
And the supercharged engine should be lighter on juice, not heavier.
