I like it. Dome has allways made sleek and low bodywork.
On the other hand,I too am no big fan of ever more and more areo similarities with single seaters. I think there's a job for the organisers here,to make sure the cars don't become to much "single seaters with bodywork" as gucom says. So,no more of these ugly highrise nosecones please!
For the rest,I must say I really like the roofline...
