Welcome along, and hope you enjoy the site.
Nice car you got there by the sounds of things.
First comment is regarding the emissions for the VRT. AFAIK, it goes on the manufacturers figures for the car, and if these aren't available, you're automatically in the highest band. Each car isn't tested individually, so you're caught paying the highest band. This is my understanding of it anyway, but I'm open to correction.
I'd say come along to one of the meets if you can, there's one the end if the next month, and you'd get to know the crew.
There is LOTS of knowlegde here. If you have questions you have a look for related topics using the search feature, but if that fails, don't be afraid to ask, all the guys (and galls) around here are very nice.
Put up a few pics if you can, and congrats on the purchase.
