I used to work with Paul Clifford one of the guys that set up dreamcars.ie. He is a nice guy but I've never dealt with him from a cars perspective. Originally they were managing high end stuff & from what I remember they took over Des Cullen Cars business too. I met him last year & they do chase down anything for customers from a CW Golf to a Ferrari.

Having said all that bringing a car in yourself is not that hard really. You just have to ensure you do all the necessary checks, book your flights & ferries, etc. arrange a VRT appointment. Finally realise tag you'll not always land a warranty.
