TURBO OR SUPERCHARGER

[JOHNDALY]

Greetings

Just about to buy a Cooper S from a main dealer but it has a supercharger not Turbo.

Apart from more expensive road tax and less efficient fuel economoy what's the main difference.?

I am sure power delivery will be slightly different (characteristics) but am
I going to end up with something that no one wants when it comes to selling it..?

If you are in the know would appreciate your help.

Thanks
