I'll do a formal trip report later during my trip when I have more time but I wanted to leave a great post about ExclusiveAirports.com. I booked with them online a few weeks ago. They promptly responded via email to confirm.
They were extremely professional and the driver was waiting right outside the gate after the baggage area. He was on time, polite and helped us with all our bags (we had alot as we are on a 1.5 month trip).
His car was a late model car in great condition and was very clean. We brought us to our hotel with no problems. The fare quoted was £39 ($65) plus we gave him a good tip. (He didn't ask for one but certainly deserved one).
I emailed a few places but most didn't answer back quickly. I found the price a bargain compared to the alternative of using a taxi. Really I'm not sure who would use a plain taxi these days from the London airports.
A shuttle or a train wasn't an option for us as we had lots of bags and a 1 year old baby with us.
I highly recommend using them for an airport pick up. Great service.
