I felt the same when I got my car, albeit it is a lease it was still via a small (unheard of) company and it all felt a bit dodgy because the deal was so good in comparison to others. They made me put my deposit down and proof of insurance etc before I'd even lay eyes on the car (I don't know if this is normal?) and they didn't really give me any proof or updates about the transaction until one day they called and said it's on it's way in a weeks time.
It was immaculate and completely what I expected of course, just found the whole process slightly weird but yeah just thought I'd share my experience.
Thanks for the reassurance
